CMS performance problem

[TamasV]

Hi all!

We have performance problem with our CMS. SIM 6.2 and IRS 5.50 are installed on a guest virtual machine on ESX 3.5 U2.
We see high CPU utilization most of the time. CMS have 4 Gb reversed memory and 2.6 Ghz 2 core CPU.
As we see mxdomainmgr.exe process has the highest CPU usage rate.

CMS OS: Win2003 SP2

We have already taken the following actions:
- Remove Vmware tools
- IN SIM we limited the number of systems that are being collected at one time.
- Increase the time between two hardware status polling task run.
- JAVA is up to date

What do you suggest?

Thanks!
