The Server resources are pretty much available. I have configured Apache Server Status and it shows me normal readings from the server. can anyone tell me the meanings of terms used in Apache server status program. can it be a network problem? Scoreboard Key: "*|_|*" Waiting for Connection, "*|S|*" Starting up, "*|R|*" Reading Request, "*|W|*" Sending Reply, "*|K|*" Keepalive (read), "*|D|*" DNS Lookup, "*|C|*" Closing connection, "*|L|*" Logging, "*|G|*" Gracefully finishing, "*|I|*" Idle cleanup of worker, "*|.|*" Open slot with no current process
I faced a similar problem with PHP and FastCGI. The problem was not of apache but of database (MySQL). Try optimizing settings for whatever DB you use.
Also compile Apache with --enable-atomic-ops and CFLAGS="-march=i686 -O3"I recompiled PHP and MySQL too with the above CFLAGS which gave me a big boost in performance.
Also set vm.swapiness = 100It swaps out processes which are not active much. But that setting should not be required for you cause you have plenty of RAM. In my case, I have exactly 497 MB of RAM.
