[solved] SuExec Daemon + CageFS = Poor Performance

[bettinz]

Hello, I've a problem, and I ask your help to find the cause:

I've Litespeed 4.2.1 LSAPI 6.1, Cloudlinux 6.3 with CageFS.

If I enable the SuExec Daemon with this settings in external app:

Auto Start : Through CGI Daemon

and Run On Start Up: suEXEC Daemon

I can see poor performance. I don't know why, but the cost of first open, is high.

With the same settings (tuning, ext app, etc), but with:

Autostart: Yes
and Run On Start Up: No

I can see old speedy Litespeed. Why?

Thanks

looks no reply from bettinz.
it's best bettinz can update this post.

that's no known performance issue so far regarding suExec Daemon + CaseFS

but phpSeletor which working with apache not working with litespeed yet -- CloudLinux and litespeed will co-operate to work on this.

one known poor performance issue is, set Cage limit too low, after adjust the limit, back to normal.

Hello in my case, the problem is solved by setting an higher value of limits. By the nature of limits, websites are a bit slower, but if website in the past can use 100% of cpu, now it's limited to 25%, so it's normal. In my case, another problem was database optimization.
