We have a 12-core Xeon server with 32GB RAM. On it we have a 1-VCPU DomU
running a Windows 2003 Std. R2 terminal server. When I run PerfMon
within Windows, I see that processor utilization runs very high, on
average 30-50%. Before we virtualized this server, it was running on a
4-core machine with 16GB RAM and processor utilization averaged 5-20%.
Why so much higher now in a DomU environment?
if it was 5-20% on a 4-core, a naïve calculation means going to a 1-core (virtual or not) should get 20-80%
doesn't sound so far off
