Friends:
I am struggling with very slow virtual machines.
I have Windows Server 2012 installed on a Dell T620. It has two Intel Xeon E5-2650 2.00GHz chips (20M Cache, 8.0GT/s QPI, Turbo) and 64 G of 1600 MHz RDIMMS. It is set up with two RAID arrays (RAID 1 for OS with two 300G 10k SAS drives; RAID 5 for server stuff with four 600G 10k SAS drives) running on a PERC H710 Adapter RAID Controller (512MB NV Cache).
There are two virtual servers running on the box. One is the domain controller and the other hosts a SQL-based practice management program. The "physical server" hosts HyperV etc.
There are 5 or 6 virtual workstations, each running Win8.1E with one virtual CPU and dynamic RAM allocations of up to 8192MB.
HyperV has two virtual switches ("RDS Virtual" and "Intel I350 Gigabit Network Connection - Virtual Switch"). (I don't actually know why it is set up that way.)
I wonder whether anyone can help me trouble-shoot my poor performance?
