Re: [otrs] OTRS is slow

12 Jun 2008

      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?

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

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.
