My client has a windows server 2003 VM running on HyperV (Windows Server 2008 x64). Previously it has 4 vCPU assigned to it but it has very high latency which I found that Windows server 2003 can only have 1vCPU assigned to it as it is the limitation of HyperV.
Now after assigning 1vCPU and configure it to reserved 100% of the 1 vCPU, the users are complaining that it is slow in performance, there will be an hour glass sitting for 5-10minutes at times. It has 3GB of Memory. Usually only 1-2 users are logged on each time.
I don't see anything else I can do to increase the performance. Please see attached screenshot of the vCPU config. Any input would be greatly appreciated. Thank you.
