httpd-mpm.conf

[strat]

I have a Q9650 with 8GB ram on centos 5.4 64bit with direct admin.

Have a busy website and notice during peak time i get very high load usage sometimes way over 20.00

this is my httpd-mpm.conf

Any tips for my config??

[localhost]

Use another web server. Or you can try to add eAccelerator.

[darkus]

Way too many connections, try taking the 1024 serverlimit and maxclients down to like 256 and turn 'KeepAlive On'

[BestBoard]

compile apache with worker mpm, and set


<IfModule mpm_worker_module>
StartServers 1-3
ServerLimit 200-500
MaxClients 100-300
MinSpareThreads 25-50
MaxSpareThreads 75-100
ThreadsPerChild 25-50
MaxRequestsPerChild 5000-10000
</IfModule>


depends on your needs..

turn on KeepAlive and lower the timeout to 20-30 seconds.

and you better replace apache with nginx.
