Thanks for the post regarding mod_perl - I was not aware of setting it
up this way!
I set this up per the README.webserver file, and noticed at least a 10x
performance improvement in OTRS 2.2.5 running on CentOS 5.x with a
2.4GHz HT P4 & 512MB RAM.
However, I'm using some additional modules (Calendar and FAQ) that are
both still slow. I don't know a lot about mod_perl, but from looking at
the apache2-perl-startup.pl script it's obvious that it's preloading
modules.
I tried adding the Calendar and FAQ modules to that list, but apache
wouldn't start, complaining about not being able to find the files
[Tue Aug 05 10:18:29 2008] [error] syntax error at
/opt/otrs/scripts/apache2-perl-startup.pl line 156, near "use
Kernel::System::CalendarEvent."\nCompilation failed in require at (eval
2) line 1.\n
[Tue Aug 05 10:18:29 2008] [error] Can't load Perl file:
/opt/otrs/scripts/apache2-perl-startup.pl for server
otrs.terraworld.net:0, exiting...
However, the files do exist at the proper location.
I added this to the apache2-perl-startup.pl script:
# calendar modules
use Kernel::System::CalendarEvent.pm;
use Kernel::Modules::AgentCalendar.pm;
Is there a better/more proper way to install my additional modules into
this script such that my calendar and FAQ modules will also be
accelerated by mod_perl?

Hi
I was browsing through the OTRS documentation and way down in chapter 21 it says "Of
course you should use mod_perl 2.0". That's all and that's probably why I didn't
enable it before now.
I found /opt/otrs/README.webserver which had a little more info, and I decided
to try and install mod_perl.
That thing is FAST! Before OTRS was always a bit on the slow side, now it
performs very quickly.
Maybe everybody on this list already knows about mod_perl and in that case I'm
sorry about this mail. But if you don't know about it, you should definitely
check it out. It ought to at least be mentioned in the installation section of
the manual.

I haven't checked it out myself but it might be worth some research.

Subject: [otrs] OTRS is slow
Hi,
We are using OTRS 2.2.5 with a MySQL Backend with 4GB of RAM and Xeon
3.06 GHz CPU.
Linux Distribution is the latest CentOS 5.1 with kernel
2.6.18-53.1.21.el5 #1 SMP.
OTRS is running on Apache httpd-2.2.3-11.el5_1.centos.3 with
mod_perl-2.0.2-6.3.el5 and perl-5.8.8-10.el5_0.2 and is having about ~
4000 tickets in database with 300 customer companies and about 700
customers.
Apache and MySQL were tuned the best I can to improve general
performance and response time.
With all these software and hardware related things, OTRS is by far too
slow, overall navigation on the Agent AND Customer interface is slow (
response times of about 1 to 2 seconds for paged display).
At this moment, I have no clue/idea about how to make it faster, I would
like to try some sort of debugging with tool like Fred but didn't find
any documentation how to implement it and makes it work ?
By the way, I tried to disculpt some of the component by doing some
tests with other software : Apache and MySQL does not seem to be the
problem as other PHP applications running on the same server are running
fast and smoothly.
If anyone is having some ideas or advises on how to debug/find a
solution to this problem, I will be glad to read your answers and share
OTRS experience with any of you.
