Hi Brett, First, thanks for your answer. We're already using mod_perl (mod_perl-2.0.2-6.3.el5) and I prefer not imagine what it could be without it as I found OTRS slow with mod_perl enabled :) BR, Laurent Brett Davis a écrit :

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.

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.

Hi Lars, Thanks for your reply, it's good to have experience from another OTRS user. Maybe you're true and I'm asking too many of OTRS as 1 to 2 seconds are the minimum response time we have and so are having also slowest response time, but so I'm wondering then why the First improvement that appear in announcement for OTRS 2.3.0beta1 is Performance : http://lists.otrs.org/pipermail/announce/2008/000093.html ? I would be very interested in having other OTRS users return of experience concerning this subject. Thks. Laurent MINOST Lars Jørgensen a écrit :

Hi Laurent,

You state that response times of 1 to 2 seconds for a page load are "by far too slow".

We are running three OTRS installations here, one of them on quite powerful hardware, and I see the same response times on all our installations. I think these are normal response times for OTRS. If 1 second is "by far too slow" maybe you should cut back on the coffee :-)

What are other people experiencing?

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? --- - Nick Bright Network Administrator Terra World Communications, LLC Tel 888-332-1616 x 315 Fax 620-332-1201 Brett Davis wrote:
