HYPER-V VM slow performance with flat file database
Posted on 2014-08-31
We have a brand new server running Server 2012 with HYPER-V role installed on it.
The configuration is HP ML350G8P, INTEL XEON E5-2620V2, 16GB RAM (2/8), 2 X 300 GB 6G SAS 15K HDD (RAID 1)
There is only 1 x VM in this server to which we have allocated 12 GB RAM, 140 GB HDD (Virtual IDE and Fixed Disk size) and 2 Core CPUs and it is also running Server 2012.
Now this VM is acting as a terminal server with a special software program running on it which runs a Flat file database. Everything is getting read and written to the C:\ drive of this server, ut this program is taking 7-8 times longer to fetch queries/generating report etc. Additionally Outlook seems to be running slow as well. What can we do to increase the performance, so it performs same as our old server which was 6 years old, running Server 2003 OS?
I have checked Resource Monitor and none of the components - RAM, CPU, DISK etc. are in stress.
Not sure what the issue is here.
