nagios 3.2.1 vs 3.2.3 status.cgi major performance regression

[Roberto Oppedisano]

We're observing a major performance regression in status.cgi, related to 
servicegroup browsing 
(/cgi-bin/nagios3/status.cgi?servicegroup=Enviroment&style=detail&&hoststatustypes=2&hostprops=0 
links and similar) between nagios 3.2.1 and 3.2.3.

Time to browse a servicegroup increases from seconds in 3.2.1 to 
minutes/timeout (having status.cgi on 100% CPU).

Simply reverting to 3.2.1 status.c (patch attached) in 3.2.3 solves the 
problem. This is on debian squeezy amd64, packages recompiled from .deb 
sources.

I've uploaded servicegroup file here:

More info on request.

Kind regards,
R
