@Joe Collins: This was an EXCELLENT walk-through! I'm a Linux Noob and people's instructions on websites were not granular enough for me. This was outstanding and very helpful! Thank you so so much!!!!!!
Never knew this or adjusted these settings - great job, Joe! I am fuzzy, but I think for my system I was told to turn off write cache due to how important the sql database was for my mythtv setup, but I might be wrong. When I was working on my click repair RT machine (video on my channel, real time click repair of vinyl records hooked up to my table), if it wasn't for rebooting via SSH, I would have worn out my legs while testing!
That would be a speical use case right there. If MySQL recommends turning it off, leave it off. You would NOT want to corrupt a database. For a desktop it's not a big deal. :)
Hi, great video. I want to mention that I've set value of 40 for swappiness value on one of my computers with 2 GB or RAM. In my experience, swappiness value of 10 is good if you do something that does not require too much memory. But when I do several things that require a lot of memory. Then Linux Mint 17.3 Mate starts with some heavy swapping, and often it takes few minutes or more. And during that heavy swapping I cant do almost anything on my computer. With swappiness value of 40, I don't have such problems. Maybe some other value will give me better results, but I'm ok for now with swappiness value of 40.
Suggestion.... Making backup copies of system config files is usually a wise precaution (in my book). In this case, I would have created a copy of "sysctl.conf" named "sysctl.conf.mmddyyyy" before making changes. ALSO.... Commenting changes in any config-file is always a good practice. :)
Joe thank you very much for the tutorial of how to adjust swampiness as I for one did not know you could do that as someone told that it was not a good idea to use a SWAP partition on my SDD which is the hard drive I am using on my laptop because it would be writing to it and it would make it it's life span of the drive shorter but now that I can adjust the swampiness I no longer need to worry about that as like you said it good to have a SWAP partition as some applications depend on it therefore I am going to leave my SWAP partition and just adjust it and bingo bob is your uncle so thank you Joe :)
FYI... All SSD's have a set amount of write cycles. The latest SSD generation lasts longer than the 1st gen-SSD's . IMO.... You will upgrade your SSD long before it has a write-fail (that is in a desktop setting). When I have created Linux Server setups with SSDs.... I have always used a dedicated standard-fast HD for the swap-partition and log-files, but only in heavy traffic and transaction cases like SQL Servers.
Thanks for these excellent tips! There is only one slight little problem: In Gnome-disks the drive settings are grayed out so I can't enter it. Is there any way around this?
You may also turn off a machine remotely if your baseboard have a baseboard management controller (BMC). you need to configure to talk to your remote machine and issue a reset/hardstop/hardstop remotely. Some high end server machines provide that support.
PS have been using Linux for about 20 some years, just never messed with Arch that much. Have installed via command line, but I really like Antergos. Just cant remember about how to set Swappines. Thanks.
Thanks for another great video, sir. This greatly improved the performance of my Pearl OS running in Virtualbox. I'll have to try it on my other machines to see if there is an appreciable difference in native hardware. Have you considered the possibility that a low swappiness factor could be affecting your system's ability to resume after going to sleep? Have you tried experimenting with higher swap usage to alleviate the problem? It was just a thought. I really appreciate your videos and I have learned a lot from you. Thanks so much.
In the 90s as a user of IBM's OS/2 Warp we had settings in the config.sys that would limit the minimum and maximum swap file SWAPPER.DAT that could be created.
Great video. Clear teaching. I like watching your videos. Thanks Joe. I use Clonezilla to do full drive backups. But could you do a video on just data backup and restore? How can I restore data on my computer after I do a complete and fresh reinstall of a Linux distribution on my computer?
I have run machines without any swap space. Did not really encounter issues in recent times with more memory. Years ago on limited memory, you did run risk of programs suddenly force quitting without it.
Thanks I got it changed...I have an issue and I know you would know..when Im typing in the terminal, the letters are like skipping, or acting like I hit the space...then they would overlap...does anyone understand what Im saying...??? thanks.
I tried installing Mint on an old laptop to get a feel for it and tried some optimization ideas, but still not impressed with the performance. I know this is more about my ten year lold laptop than any shortcoming of Mint. I have Cinnamon as my desktop and I am thinking that Cinnamon is too much of a memory load. Also using Chrome might be a big memory issue? do I need to re-install Mint to switch desktops?

Is it safe to enable APM in Gnome Disks? 16:57 - my Music-PC's IP Address is 192.168.0.7 his is 192.168.0.17, I thought it was kinda weird the our machines have the same (almost the same) assigned IP Addresses... all I have to do is add a 1 in the xxx.xxx.0.7 area of "MY" IP Address for ssh (i don't think i can ssh another machine over the internet.)
Teamviewer works great! For somebody change from Windows to Mint well not so fast. An older friend was using IE (imagine...) so I installed Google Chrome and voilà. Installed all her links etc. Now if can only find a free Cribbage game (GUI) for Linux that would do it LOL.
First of all thank you very much for all the helpful tips you give through this channel. I tried the tricks suggested in this video and yes i found that swappiness in ubuntu gnome 16.04 (the one i'm using right now) is 60. And then I changed swappiness to 10 as suggested, then double checked using "sysctl vm.swappiness" and found that it was reduced to 10. The problem is that I've got 4 gigs of ram in my laptop and the swap partition is 4 gigs (didn't mess with the system defaults while installing) and despite that fact, the system started to swap although i didn't reach the 90 % limit of memory usage. I checked using htop. And yes I restarted the computer after setting swap to 10. Any ideas will be much appreciated.
I'm giving this a go for one reason. To see if it improves the performance of the libreoffice suite. In particular the Base module. There has always been a problem with it freezing up especially during an edit, but the problem is getting worse. If i do not find a solution soon i will be forced to abandon Libreoffice for another option. Kexi may become my next database platform.
I don't usually do that myself so I have never tried to remove it. I did find this thread, though. askubuntu.com/questions/107410/can-you-unencrypt-remove-encryption-from-a-user-home-folder
A test by The Tech Report - _"The SSD Endurance Experiment: They're all dead"_ showed the worst SSD starting to reallocate sectors, only after 100TB written. I think you can swap a long, long time, before SSD writes become an issue.
If that's the same test I'm thinking off, you're way off. That was around 1 to 1.2 PETAbytes written before reallocating sectors. That website had Samsung 840 pro, one or two Kingston ( one of which was a Hyper x I think), Corsair Neutron gtx, and I forgot the other off hand. The 840 pro won the fight in longevity with just over 2 Petabytes of data written and it still had some space that was usable.
No. The Samsung 840 started reallocating sectors at 100TB, uncorrectable errors following around 300TB and it's death at 900TB. The best in the bunch, the Samsung 840 Pro started reallocating sectors at 600TB, uncorrectable errors only at the end and died after 2.4PB. The Samsung 840 was the only TLC NAND, the others, including the Samsung 840 Pro, were MLC, which is more robust but is yesterdays technology and probably won't be seen in the future. So I won't make an argument about how durable SSD's are, with the single most durable SSD, based on a technology not reflecting the current market ... that would be dishonest. I take the worst SSD and show it's still better than anyone expected. Who's to say someone isn't using the Samsung 840, I can't tell them they don't have to worry with SSD's up until 1PB written. I don't know about you, but to me a drive needs to be replaced the moment it starts continuously reallocating sectors, because uncorrectable errors will follow fairly certain and even for a swap drive, that's unacceptable to me.
I am still a newbie. I have a high-quallity SSD with 480 GB. I have several distros on it, and playing with all of them using a boot-manager called rEFInd. Anyways, I had no clue what I was doing when I installed everything and have dozens of partitions and several swap partitions. I am sure my partition arrangement is clusterf**k. But it works. So do I need to set swappiness for each distro ? How do I get each distro to share the same Swap Partition ? And once I set swappiness to 10, how big does the Swap Partition need to be ? I think my main goal at the moment is to set my partition for the primary Linux distro to something like 80 GB, and then only set the test distros to something like 20 GB. But even that is over-kill. Right ?
Really like it too. Only real issue I have is the panels sometimes don't load properly in Ubuntu MATE when logging in (like missing network, clock) so have to log out and back in again. Doesn't always do it so hard to pin the cause. Caja also sometimes randomly locks up.
I had an issue with Caja especially when left opened long time. I replaced it with Thunar and everything was cool (thunar has a very simple interface, but you it has a lot of addons so you can make it looks like anything you want)
Hi Joe great video on Swappiness. I just have a question a little confused about this. Is this the same thing as to when you create swap partition in Ubuntu based when installing. A little confused because i thought swap file had to be how much ram you have in your pc. So when you where saying used 60 just confused how that works. I have my swap partition 16GB because that's how much ram i using and its pretty good ram fast too. SO i just want to know if that 60 is this the same thing and how is that is the 60 less then 16GB. Just lost if you can help me understand. Thank you Another thing is talking about swap. I seem to have no idea how that is supposed to be used or if i'm actually using it. I know i have to make it on Ubuntu based every time but how exactly is this supposed to be used to get full extent of using it. I have heard that its good to have if something happens to your system you can get it back. But to me its just nothing to me its just there in way and i would like to use it and know all i can if you can help me understand this part of swap Thank you Joe hope you understand all my wording
I'm not Joe, but I think I can help. The 60 part is how much percent of ram needs to be unused for your system to start swapping. (ex. if it is set to 60, then when 60% of ram is left, unused, then the system will start using the swap partition) Swap memory is slower than ram. Swapping is useful for when your system enters suspend or hibernate mode. It is also useful when you run out of ram.
Thanks To Worry. I usually never use suspend or hibernate i always like my pc running. ONly because when i used windows i was told it was bad thing. So i get the 60 part now that i got. so like when i make swap partition 16GB of my ram capacity size. when you say run out of ram what do you mean by that. 16GB isn't enough ram. I can go and get 32GB of ram at Max :)
+TJ Wolf 16GB is more than enough for most computers. When your ram runs out, all of your 16GB are being used, You can get it back by closing apps or programs using it.
Just a taught about sleep issue you had with LMDE. I noticed that you have Intel graphics. Thing is that debian decided to put new intel gpu drivers to testing repository. I faced similar issues with my Broadwell based laptop with integrated Intel Broadwell-U GPU. More on that here: www.slightfuture.com/how-to/debian-newer-intel-graphics
Yes, yu should turn it on... It's actually on be default these days anyway but activating in Gnome Disks gives you control over it. Swap space on SSD is not a big deal these days, either.
hi I have a problem I did everything and it worked but when I turn off the computer and put it on again the swappiness was at 60 again, help I dont what is wrong
Don't put the swapiness at 1 in a low end machine, this is awful, is going to be quick in certain scenarios, browsing the web, opening applications, but when the system get stresses by different processes is going to freeze. The best is using something like 30 in these kind of machines, there is a reason why the default to 60 in the first place.
That's only set to 60 by default to accommodate server machines and low end machines with less than 3GB's of ram that people also use to run 10+ tabs of google chrome. Run all of your commonly daily used programs at the same time , open up your System Monitor ( gnome-system-monitor if on LInux Mint ) and select that Resources tab/button and see how much ram you're using. If you still have at least 15% ram or more remaining versus the physical maximum you have in your PC, then having 60 swappiness is asinine and it needs to be lowered big time...say down to 5 or 10 at most.
11 years of using Linux and I never knew about adjusting swappiness...still learn something every day. Yay memory management.
It's been two years but same here hahaha.
1 month here but since its for a very old laptop I need to use every single trick I can find!!!
A week here.
@@openlink9958 me too
A hour here
@Joe Collins: This was an EXCELLENT walk-through! I'm a Linux Noob and people's instructions on websites were not granular enough for me. This was outstanding and very helpful! Thank you so so much!!!!!!
I knew about swappiness but didn't know about setting write cache. Thank you.
I must have missed alot of these videos. But I am enjoying them now. Thank you!!!
That is the great thing about Linux you plate will never be full.... Thank again Joe..
Thanks for the advice for devices with low memory (7:35). I have a netbook with 1 GB of RAM, so this is great.
I've been using Linux Mint for two years. But I still feel like a newbie. I'm continuously learning something new.
Thanks for the write caching step it helps my xubuntu 16.04 2gigs ram 32 bit system...Love your videos for months .....
I didn't know I could adjust the swappiness! Thanks Joe.
Never knew this or adjusted these settings - great job, Joe! I am
fuzzy, but I think for my system I was told to turn off write cache due
to how important the sql database was for my mythtv setup, but I might
be wrong. When I was working on my click repair RT machine (video on my
channel, real time click repair of vinyl records hooked up to my table),
if it wasn't for rebooting via SSH, I would have worn out my legs while
testing!
That would be a speical use case right there. If MySQL recommends turning it off, leave it off. You would NOT want to corrupt a database. For a desktop it's not a big deal. :)
Thank you so much! This procedure doubled my framerate.

I am glad Mr wizard is back!!
Thanks. That just helped my aging ThinkPad out immensely.
can also use preload (apt install preload) this will remember your frequent used programs for fast loading next time you use it
FYI... All SSD's have a set amount of write cycles. The latest SSD generation lasts longer than the 1st gen-SSD's . IMO.... You will upgrade your SSD long before it has a write-fail (that is in a desktop setting). When I have created Linux Server setups with SSDs....

Always enjoy your vids and tips.
Thanks for these excellent tips! There is only one slight little problem: In Gnome-disks the drive settings are grayed out so I can't enter it. Is there any way around this?
Is it the same case with ZRAM? I mean the zram compression should start at 90% of physical memory usage if I set 10 to swappiness
You may also turn off a machine remotely if your baseboard have a baseboard management controller (BMC). you need to configure to talk to your remote machine and issue a reset/hardstop/hardstop remotely.
Some high end server machines provide that support.
Is it really require to reboot after adjusting swapiness parameters to be effect?
Sysctl -p wouldn’t enough to effect the changes ?
Yes.
Thanks Joe. You always surprise me.

Hi Joe,
little bit off topic. what theme ur using on ur host machine?

Yea Linux Mint has been for me weird too, especially the newer OSes. Im actually back on XUbuntu currently 18.04 and upgrading to 20.04
I am still a newbie. I have a high-quallity SSD with 480 GB. I have several distros on it, and playing with all of them using a boot-manager called rEFInd. Anyways, I had no clue what I was doing when I installed everything and have dozens of partitions and several swap partitions. I am sure my partition arrangement is clusterf**k. But it works. So do I need to set swappiness for each distro ? How do I get each distro to share the same Swap Partition ? And once I set swappiness to 10, how big does the Swap Partition need to be ? I think my main goal at the moment is to set my partition for the primary Linux distro to something like 80 GB, and then only set the test distros to something like 20 GB. But even that is over-kill. Right ?
great great video . waiting always for your great works i learn a lot from you thanks for your time .
Joe please come back and post on youtube
Does kernels update themselves or do you have to do it manually by yourself?
It depends on your distro. Ubuntu automatically upgrades Kernels, Mint holds them back unless you allow it to install them.
+Joe Collins (EzeeLinux) Thank you so much, you're awesome :)
You are a good man. Thank you !
Why does Mint not come with swappiness already set lower? Mint is not a server OS.
Stability across a wide variety of systems. 60 is a good number for making sure the memory doesn't get maxed out too soon on 4 GB or less. :)
I keep hearing people using ssd when running Linux what’s the advantage or benefit of the ssd?
SSD's are fattier and more reliable than spinning drives these days. :)
@@EzeeLinux ahhh I see
@@EzeeLinux I may invest in a cheap one just to test the hype
I would like to know how you did exit the terminal
Probably Ctrl+D.
UBUNTU MATE is awesome i am using it and everything works fine.
Really like it too. Only real issue I have is the panels sometimes don't load properly in Ubuntu MATE when logging in (like missing network, clock) so have to log out and back in again. Doesn't always do it so hard to pin the cause. Caja also sometimes randomly locks up.
I had an issue with Caja especially when left opened long time. I replaced it with Thunar and everything was cool (thunar has a very simple interface, but you it has a lot of addons so you can make it looks like anything you want)
Hi Joe great video on Swappiness.
I just have a question a little confused about this. Is this the same thing as to when you create swap partition in Ubuntu based when installing. A little confused because i thought swap file had to be how much ram you have in your pc. So when you where saying used 60 just confused how that works. I have my swap partition 16GB because that's how much ram i using and its pretty good ram fast too. SO i just want to know if that 60 is this the same thing and how is that is the 60 less then 16GB. Just lost if you can help me understand. Thank you
Another thing is talking about swap. I seem to have no idea how that is supposed to be used or if i'm actually using it. I know i have to make it on Ubuntu based every time but how exactly is this supposed to be used to get full extent of using it. I have heard that its good to have if something happens to your system you can get it back. But to me its just nothing to me its just there in way and i would like to use it and know all i can if you can help me understand this part of swap
Thank you Joe hope you understand all my wording
I'm not Joe, but I think I can help.
The 60 part is how much percent of ram needs to be unused for your system to start swapping. (ex. if it is set to 60, then when 60% of ram is left, unused, then the system will start using the swap partition) Swap memory is slower than ram.
Swapping is useful for when your system enters suspend or hibernate mode. It is also useful when you run out of ram.
Thanks To Worry.
I usually never use suspend or hibernate i always like my pc running. ONly because when i used windows i was told it was bad thing.
So i get the 60 part now that i got. so like when i make swap partition 16GB of my ram capacity size. when you say run out of ram what do you mean by that. 16GB isn't enough ram. I can go and get 32GB of ram at Max :)
+TJ Wolf 16GB is more than enough for most computers. When your ram runs out, all of your 16GB are being used, You can get it back by closing apps or programs using it.
Just a taught about sleep issue you had with LMDE. I noticed that you have Intel graphics. Thing is that debian decided to put new intel gpu drivers to testing repository. I faced similar issues with my Broadwell based laptop with integrated Intel Broadwell-U GPU.
More on that here: www.slightfuture.com/how-to/debian-newer-intel-graphics
Thanks for the feedback.
so bascially should we enable write-cache in SSD ? It doesn't lower the ssd's life as the swap partition does, right?
Yes, yu should turn it on... It's actually on be default these days anyway but activating in Gnome Disks gives you control over it. Swap space on SSD is not a big deal these days, either.
Thank you the reply!
Use DHCP and/or ARP MAC to IP pairing reservation.
Awesome video. Thanks.
hi I have a problem I did everything and it worked but when I turn off the computer and put it on again the swappiness was at 60 again, help I dont what is wrong
You didn't save the changes to the file. Try it again. :)
Ok 1 ssd for boot 1 for swap, 2T junk file
Suspend writes RAM contents to disk, which could be bad for an SSD.

Be careful Joe. Don't install Linux Debian while both you and the computer are sleeping.
New kernel breaks the system. That's shocking
Adrian-Cornel Borină im running 4.16.rc1 lowlatency and its great. Im a windows 10 insider and every other windows build gives bsod.
Don't put the swapiness at 1 in a low end machine, this is awful, is going to be quick in certain scenarios, browsing the web, opening applications, but when the system get stresses by different processes is going to freeze. The best is using something like 30 in these kind of machines, there is a reason why the default to 60 in the first place.
That's only set to 60 by default to accommodate server machines and low end machines with less than 3GB's of ram that people also use to run 10+ tabs of google chrome.
Run all of your commonly daily used programs at the same time , open up your System Monitor ( gnome-system-monitor if on LInux Mint ) and select that Resources tab/button and see how much ram you're using.
If you still have at least 15% ram or more remaining versus the physical maximum you have in your PC, then having 60 swappiness is asinine and it needs to be lowered big time...say down to 5 or 10 at most.
