Litespeed + cPanel + Cloudlinux

Until this gets implemented, a simple workaround will be to use "ionice" to de-prioritize the high IO processes. Run a cronjob every 1-minute to detect high IO process and apply ionice to them. Just my 2 cents.

Hi does your CL have any benefit besides resource control?

We have client who has php processes that max out all cores time to time, how would ths be controled?

Make yourself some extra money and upgrade them to a dedi? Tell them to fix their code?

Well enabling PHP caching again solved it mostly and limiting php processes. Wordpress eats a lot

We only use litespeed due to better memory management I honestly don't feel quicker page loads, bout same as apache under load before it'd hang up. However the loads are smooth, no matter what the req/sec it's solid and from the munin graph it looks rock solid so I'm beginning to find LiteSpeed worth the cost already.

Enabling PHP caching again stopped the high cpu loads randomly (PHP proc's of wordpress love to just spike to 60/90 even 99/101&#37 so if some client's get a burst and their blog is running like crap

XCache knocked the CPU usage down amazingly , didn't eralize how much benefit it was since I've used it for 3 years straight, our box would just swap though so obviously LiteSpeed does somthing right with PHP

What I also mean is any site like wordpress etc can spike up a good ammount of CPU usage, getting it limited would be nice, I only want people able to use 150% in total from PHP for example, that'll stretch our 4 cores further, then when we pop another cpu in even further.

This is exactly what we are controlling when we say that we control resources.
We will not allow client's PHP processes to use more CPU resources that you set the limit too. As the result, he will not be able to affect any of your other clients.
This is also the reason we started with CPU/entry processes -- this limits are the most commonly bridged in shared hosting.

It seems Litespeed now has the ability to turn on/off CL. I turned mine 'on' in the admin panel, but it doesn't seem to be working.

Has anyone had any issues with 4.0.16 Litespeed and CL?

Try a force reinstall to make sure using the latest build. there are LVE related log entries in stderr.log, you need to enable PHP suEXEC.

I installed it today, nothing in stderr.log for lve

[mistwang]

Every time you start LSWS, there should be a LVE log entry in stderr.log

check pid of lscgid,
lsof -p <pid_of_lscgid>

it should list liblve library and /dev/lve there.
