Hi all,
Forewarning: I sort of got this stuff dumped in my lap so I am by no means close to an expert in virtualization. I apologize in advance.
Scenario:
We are using Hyper-V VMs as our build machines (Windows 7 SP1 64-bit guest OS) for all of our products. Right now I'm trying to shave time in the main solution compilation times for the one project and have been getting hardware increases on the Hyper-V host server.
The IT admin ran SQLIO on the host (Server 2012 - not R2) and saw numbers like:
IOs/sec: 28259.00
MBs/sec: 220.77
I ran SQLIO on the VM in question and saw numbers like:
IOs/sec 4070.33
MBs/sec: 7.94
Now the host hard disk setup is 2x 10k SAS drives. I've tried plugging an SSD in and sticking one VM on there and re-running and saw no increase.
This is leading me to believe there's a wonky configuration somewhere. I have the drive set to a fixed-disk vhdx on IDE controller.
Any ideas?
