Hello, i'm facing a problem with my site , it has a lot of traffic and it loads very slow , ~30-40sec.

First i found the problem when i got some 500 internal errors , i found that IPCCommTimeout 31 , was to low and i changed it to 60 , now i don't get 500 errors but the site loads really slow , ~40 sec ...

I think fcgi is under heavy presure and i doesnt work as expected...

can you provide me some information in order to make things better ?
