Folks, I'm wondering if you can help me tweak my Apache. You see, I'm
an Apache newb essentially. I set up my webserver to do two things,
Squirrelmail and Subversion, and the security is pretty well locked
down, as far as I could follow those instructions (everything runs
through https).
Now, I am the *only* person who uses either of them, so it's not like I
have a huge need for multiple processes, yet, from top:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
16300 apache 16 0 15736 6700 4812 S 0.0 0.9 0:00.00 httpd
16301 apache 16 0 15732 6684 4808 S 0.0 0.9 0:00.01 httpd
16302 apache 16 0 15732 6684 4808 S 0.0 0.9 0:00.01 httpd
16303 apache 16 0 15740 6764 4852 S 0.0 1.0 0:00.01 httpd
16304 apache 16 0 15836 6788 4872 S 0.0 1.0 0:00.01 httpd
16305 apache 17 0 15736 6700 4812 S 0.0 0.9 0:00.00 httpd
16306 apache 16 0 15732 6692 4812 S 0.0 0.9 0:00.00 httpd
16307 apache 16 0 15732 6684 4808 S 0.0 0.9 0:00.01 httpd
29990 apache 16 0 15732 6684 4808 S 0.0 0.9 0:00.00 httpd
29991 apache 16 0 15736 6696 4812 S 0.0 0.9 0:00.00 httpd
29992 apache 16 0 15736 6700 4812 S 0.0 0.9 0:00.00 httpd
29994 apache 15 0 15732 6680 4808 S 0.0 0.9 0:00.00 httpd
Obviously, these aren't exactly destroying my resources, but this is an
old machine, so I'd like to reduce the number of processes sort of on
principle.
My question is, what in httpd.conf should I change? I have to server
bits, and I'm not sure what to touch:
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
</IfModule>
or
<IfModule worker.c>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
It could be possible that what I need isn't these, but they looked most
promising.
Thanks for any help,
Matt
