Is it possible to install Litespeed when there are already running domains on the Plesk server?

[@litespeedtechnologies]

Plesk is commonly installed with Apache. In this case, you can even if domains are installed, switch freely between both Webservers (Apache and Litespeed) because Litespeed acts like an Apache drop-in.

Dear litespeed, I was going to buy a host but then decided to go with a VPS. The host provider at the time said that their shared server was based on litespeed. The question is, when I go and install litespeed on my VPS will this be the as if I had hosted my website on the shared host with this being based on litespeed on the provider side? Will I have the same performance>?

[@litespeedtechnologies]

This might depend on many factors such as your traffic and website structure. However, in general, a VPS (depending on the size) should be more performant in comparison to a shared hosting account.
