Hello all, Environment: ESX 3.5 U3, VC 2.5 U3, HP C7000/BL480c G1 Blades, EVA3000/EVA4000 Problem: We are experiencing intermittent performance issues on some of the virtual machines. Can't really find the reason. Problem is sluggish performance in GUI, some actions time out or takes too long time. VM's are Windows Server 2003 with latest VMware Tools and updates. Deployed from template. Some actions take forever. Example: When installing SQL 2005, the setup scans the system for installed components. This takes normally 5-10 secs with ~70% CPU load. When problem occurs this takes 4-6 mins and the CPU is at 100% during this time. Since this is the pretty much the only way I have been able re-produce the problem I used this SQL Setup scan as a benchmark. All kinds of combinations on different vm's, vm configurations, Windows settings, hosts, datastores is tested and timed. Observations: When pagefile is moved to another disk it sometimes improves performance </div> Using a local account during setup solves the problem, still the source of the problem is unknown We have no known hardware, network or Active Directory issues. A VMware health check was conducted 6 weeks ago. No issues were found that could cause these problems. Remember that problems only occurs in the virtual environment. Any suggestions on how to move on with the troubleshooting are highly appreciated! Thank you! Björn
