1 Host Server running HyperV, Server 2008R2 Core
4 live VMs all stored on 1 separate physical disk (separate from the boot drive)
The DC is virtualized on this server as well
Roaming profiles are enabled
A Terminal Server VM has about 35 users and doesn't have any performance issues throughout the day (light use: firefox, office etc.) but in the morning when many users are logging in, the system has serious performance issues.
Any thoughts on what I can do to improve performance?
