A Realistic Assessment of the Performance of Windows Guest Virtual Machines by Mark Friedman and Stephen Marksamer

This guy will make your head hurt.  I know, I used to work for him. However, he really knows his stuff. In summary, he’s pointing out that Widows performance metrics on ESX guests are impacted by system timer value inconsistencies related to virtualization.  The net-net is that all timer-based measurements can be affected. This includes % Processor Time, for Thread, Process, and Processor level and the Avg. Disk Secs/Transfer response times for both Logical and Physical Disk.

 

Very cool thanks Mark.  Now when I blame all those pesky Tivoli problems on VMware I can point to this article.
