Hello,
My clients are complaing for slow servers .There is no network speed problem or mysql problem as I already optimizade mysql ..
But still server is running slow..
Here are some of my parameters:

Check this:

server# ps -aux | grep -c http
231
server# ps -aux | grep -c mysql
2
server# top d 1
last pid: 61284; load averages: 0.41, 0.45, 0.39 up 50+16:19:21 08:03:55
309 processes: 1 running, 308 sleeping
CPU states: 18.8% user, 0.0% nice, 11.5% system, 1.0% interrupt, 68.8% idle
Mem: 319M Active, 165M Inact, 451M Wired, 35M Cache, 111M Buf, 16M Free
Swap: 2048M Total, 12M Used, 2036M Free

And in httpd.conf file I have:
Keepalive on
MaxKeepAliveRequest 500
MinSpareServers 5
MaxSpareServers 10
StartServers 5
MaxClients 230
MaxRequestsPerChild 0

How should I tune this?
Thank you

What sort of hardware is this? What version of FreeBSD are you running? What sort of traffic are you serving? How much traffic are you serving?

I'd start by increasing MinSpareServers and MaxSpareServers to 20 and 60 respectively, with your current numbers you're wasting cycles on forking. Beyond that, I'd need to know some details (see questions above).

show
apachectl status

and attach full httpd.conf
