help with mpm_worker setup

[PPNSteve]

been having apache2.2 crashing a lot lately (was using prefork) so decided to rebuild with the worker mpm in hopes that it will better use our available resources.

now i just need some real-world help configuring the settings for the worker module

avg users on this box at one time is around 350 - 400 (hosts a vB forum, so its 95% php/mysql) so we'd like to set a max at 625 clients/users etc. to handle the peaks.

we have 2GB ram so resource usage needs to be minimal

apache's default:

 
ServerLimit 16
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

our current (best guess) settings:

ServerLimit 25
StartServers 2
MaxClients 625
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 1500

now can some of you using this module help me come up with workable settings to handle our userloads??

suggestions? your recommendations please.

thanks in advance.

My suggestion is that MaxClients 625 is a lot for only 2GB of RAM.


Thanks,
