Bernd, each CPU has many cores. If you have six cores, then 4 * 6 = 24 cores.
BIOS is the latest for that server, which is old.
OS for the host server is Windows 2008 R2.
At this point I believe the performance issue may be related to slow graphics card on the server, and I am bringing up the virtual machine on the VM Workstation console on that server. I need to connect to the VM by Remote Desktop on a computer with better graphics and then I'll have a better idea of where the performance bottleneck lives.
