I run 2x 10 Gbe Between a Mac Studio M1 and a Ugreen NASync 6800 Pro. The former uses a TB4 IOCREST adapter (~US90 on Aliexpress) paired with the built-in 10G NIC. The latter is running TrueNAS Scale with two motherboard onboard 10G NICs. I get 2GB/second copying a single 108GB file to and from a PCIe 3.0 x4 SSD in the server and the internal drive on the Mac. I only have one additional IOCREST adapters so can't do a 3 channel test. Your drives are likely a bottleneck but there are also lots of stories about struggles when scaling single client performance beyond 25GB or so without serious SMB software tuning and hardware (client and server) hardware. One thing that might come into play is the way your network is configured. Scale requires that each pair of NICs be on a different subnet. Is that the case with your Synology? If not, you might try seeing if that makes a scaling difference although I suspect that your drives may make hard to tease out beyond two channels. But maybe you can match the 2GB I've gotten with a single large file (transfers start to slow quickly with macOS with lots of files)
Thanks for letting me know your setup and experience. It sounds very effective for both cost and performance. The QNAP works with all the NICs on the same subnet. I know it works because that's how I ran the tests. Like you, I believe the storage is my bottleneck for now. I look forward to getting storage that way exceeds 25Gbit to see if the SMB bottle neck you mention is there for me. I appreciate you commenting. Thanks!
I think the storage is limited to about 2400MByte/s but that doesn't explain the diminishing returns for adding NIC's 2 and 3. Have you had a different experience with SMB MC?
plus, the issue might be that 3 of 4 NICs that you are using are Thunderbolt, not sure if that's not shared somehow in your system, best case scenario would be 2 PCs with tons of PCIe lanes + a lot of PCIe NICs...

this seems like there's a bottle neck somewhere.

@@matthewdaley7535 just try that on FAST ramdisk?
