Apache MPM Prefork (default) or Worker for I7?

[chrismfz]

On servers with newer I7 or Xeons (4 cores hyperthreading 8 cores)
does anyone made tests which module runs better on Apache?

EasyApache uses by default Prefork.
I am testing both in one live server
with only one php site without heavy use
(200-300 users avg 40-50 req/sec)

and I see that with worker it's a little faster.
I am little worried about server load which reaches and exceeds 1.5
and that's ridiculous if you think that one I7 920 serves only one site
but anyway I can live with that.

I don't know if with Prefork and other configuration than default
may benefit those CPUs, that's why I am opening this thread,
to see any opinions and other experiences with those modules.

Hi

Please give MPM_Event a try and mod_fcgid if you use lots of PHP, ensure you have ram.

Also pop open google and learn to tune a system, sometimes a load of 1.5 could be normal.

Google is our friend but it just may be Drupal's problem (yes this one site is drupal based) and when they bloat it with almost every module they see it's going mad...

I am using and testing now with Fcgid and Worker MPM. suExec on and I got
status like that:

Server Version: Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 mod_fcgid/2.3.5

Anyway I will test Prefork again tomorrow to see loads/performance with
the same visits - requests and Event maybe the day after tomorrow why not...
