Solved: OTRS CPU Hungry

[RBehr]

We have OTRS 3.0.6 running on a dedicated dual-core Windows 2003 Server with a separate Microsoft SQL Server 2005 database. We have a small environment, still largely in development before a larger roll out, and will have no more than six or seven users logged in at any one time.

OTRS is running very slowly, the bottleneck being the processors on the OTRS Server. This is especially noticeable with any call to edit the SysConfig - this can cause a delay of upwards of a minute. Perfmon on the OTRS Server shows the CPU maxed out.

Given the small scale of our deployment, the server hardware should be adequate (I can give full spec if required). Any advice on tuning performance would be welcome.

Many thanks.

did you already check this? http://doc.otrs.org/3.0/en/html/performance-tuning.html

I will review and test all options in this article and then come back if this remains a problem.

Many thanks!

Sysconfig being slow is most likely due an unperforming XML parser.
In case OTRS itself is slow, make sure perl runs integrated in your webserver and not as CGI application.

Thanks ferrosti. The XML parser is not mentioned in the link supplied by Wolfgangf. Any chance you could give me a few pointers?

[ferrosti]

Nope, sorry, I run all my machines on linux. They are less expensive and perform better

[RBehr]

Yeah... we're giving some thought to moving OTRS to Linux or some other flavour of UNIX.

I'll have a look for some Windows pointers in the meantime. Thanks.
