Hey everyone. I hope this is a proper place to ask for help. So we're
having massive performance issues where our CMS got relly good loading
times using curl, but as user just using the cms we having peak times which
are 3-10 times slower. Peak times doesn't mean when many people are using
the system. I have the same issue when I'm the only one using the system.
So I wanted to profile what takes so long.
My Apache got a pretty default httpd.conf which includes 2 vhost.conf
files. I tried multiple configurations but I can't get NYTProf running
properly so I just share the current state:
I added the following lines into my vhost1.conf file:
PerlSetEnv NYTPROF file=/HAimperia/nytprof.out:addpid=0:endatexit=1
<Perl>
use Devel::NYTProf::Apache;
</Perl>
<IfDefine NYTPROF>
MaxClients 1
MaxRequestsPerChild 0
PerlModule Devel::NYTProf::Apache
</IfDefine>
I started the apache and everything seems fine. There are files created in
/HAimperia/. I click once in the CMS and I stop the apache.

1) Why does I still get multiple files even with addpid=0? I assumed
without addpid it would store all in one file.
2) neither nytprofhtml nor nytprofmerge works for me.
Am I doing something wrong? I appreciate every kind of help and advice.
Thank you in advance.
Regards, Mike.
