I'm new to Apache to my environment too.
We run 4 Apache V2.0.52 I've seeing high load averages (of 3 to 13)
reported by top on the Linux RHES 4.6 for the 1, 5 15 minutes avgs
on 3 of our webservers. All the servers' CPU are generally idle except
one webserver which sometimes hit 90-100% CPU

I will mod fstab and reboot one server at a time...
I thought there was a way of dropping atime in real time without a reboot so
you can test performance differences without rebooting
but I could be mistaken

Nor sure I understand where you say memcache is slow, we uses memcache
for session variables and for mysql query
This went well until there were not too many files on the file system...
Our experience here has been this: We're on ext3 and caching (on disk) several
hundred thousand files using mod_disk_cache. We got
worried we were going to have too many files but using df -i below shows
we're at about a
Nor sure I understand where you say memcache is slow, we uses memcache
for session variables and for mysql query caching. I did not think
there was anything as reliable and fast or faster than that? Can you
elaborate on file-based-cache fro mysql querrie?

I commented out mod_dir and Apache would not start
Yep, you'll need that one. You probably will not need the below list but you
kinda have to read up on what each module supports and
see if you're using any of those things.
mod_userdir.so
mod_usertrack.so
mod_status.so
mod_logio.so
mod_cgi.so

experience with that. I do

We also use New Relic and new PHP performance tuning tool, its very cool...
Oh, and remember to remove/comment out any PHP modules you aren't using. Every
PHP module you load (like the GD image module which
is loaded by default that people don't often use) is loaded up into the Apache
server

Hello all my first time posting , so please be gentile. :)
We have 5 Apache 2.2.3 web servers behind a HAproxy load balancer. Each web
server is a Quad core Xeon E5405@2.00GHz with 16 gigs RAM and a hardware
RAID 1 of 300 gigs
Apache is configure in prefork mode, as per Centos 5.5 install
