Optimization Ubuntu to handle big traffic

AdamM

Hi everyone!
There are certainly more experienced people here than me.
What tasks do you perform to increase Ubuntu's performance? From the system level? To support a large number of client websites on 1 server.
Of course, let's skip the hardware issues

I will be happy to talk to you and exchange my experiences

There isn't really much to be done from an o/s level. If you are running very high traffic or trying to cope with DDoS then there are kernel setting which can be tuned but generally the "out of the box" defaults are good.

Also with Enhance not having a per-server licence cost you will generally find it more efficient to run smaller servers with fewer websites per server.

That's one of the two things that I love about Enhance and that are driving us to use it.

Adam Very interesting insights. What about the optimization of LSWS?

There's some tweaking there to be done especially setting the maximum number of concurrent PHP processes that can be created by LSWS for each user. max children process limit
There's some info here: https://docs.litespeedtech.com/lsws/cp/cpanel/tunings/
