status.cgi performance problems.

[Alessandro Ren]

     We have a nagios system with 6000 services and 300 hosts and when 
many users access it simultaneously, stagus.cgi sometimes takes up to 20 
seconds too answer, so does the tac.cgi and extinfo.cgi, that status.log 
parser drags all the cpu.
     I patched the code to store status.log on memcahed, but the gain in 
performance was not great, I also stored objectscache, no speed 
improvement. So I am thinking about storing the already parsed 
structures in memcache to see.
     Does anyone knows any good seralization library to serialize the 
nagios structures or a way to improve perfomence?

     Tks.
