How many domains are you running?

[pgentoo]

killburn, are you still using the PHP_FCGI_CHILDREN setting in your php5-fcgi-starter scripts?

I posted in some thread a while back about removing that setting, and allowing fastcgi/fcgid to control all the processes itself. THis has helped me a ton, as most of the sites i host get hit very infrequently. Those processes are now allowed to die off and not have the set number always running.

Granted, I only have 23 actual accounts on my system as i'm still working on migrating people over (many more domains though), so i don't have the same scale problem as you, but I saw a HUGE change in making this configuration change.

For instance, here is what i see on my production system right now:

# ps aux|grep php-cgi |wc -l
11


Here are my current mod_fcgid settings:

Code:

IPCConnectTimeout 90
  IdleTimeout 300
  IdleScanInterval 120
  ProcessLifeTime 900
  MaxProcessCount 200
  DefaultMinClassProcessCount 1
  DefaultMaxClassProcessCount 5
  IPCCommTimeout 300
  BusyTimeout 300
  BusyScanInterval 120
  ErrorScanInterval 3
  MaxRequestsPerProcess 500
  ZombieScanInterval 3

in my php5-fcgi-starter I commented out as follows:

Code:

#PHP_FCGI_CHILDREN=2
#export PHP_FCGI_CHILDREN
#PHP_FCGI_MAX_REQUESTS=500
#export PHP_FCGI_MAX_REQUESTS
