mod_perl slower than mod_cgi - why???
Hi,
my test-system is build of
* otrs v2.2.3
* sles10, sp1
* apache2
* mysql5
The problem is that otrs runs about 10% faster with mod_cgi compared to
mod_perl2
Why???
And further:
After an apache-restart, phpmyadmin tells me that 5 db-connections from
otrs are sleeping. With every http-request, further connections are
established with a maximum of 12 connection. Is this correct?
(My productive-system on suse prof 9.3 with apache1.3 and mysql4 runs
about 2-3 times faster with mod_perl compared to mod_cgi - that's what I
expect and what I also want to achieve on my test-system.)
My config is attached.
Any help appreciated.
Bye, Alex

I just recognized that my productive system is also even slower with mod_perl1-enabled. But I know that it was must faster in the past with enabled mod_perl1. How can I analyse if the preloaded-otrs-modules from apache2-perl-statup.pl are used within every page-request? How can I analyse if otrs opens a new DB-connection or reuses a persistent connection? How can I analyse which part of the whole system could be the slowing one? Sorry for that unspecific question - I really don't have any more ideas? Bye, Alex Alexander Scholler schrieb:
