Terminal Server Slowdown
Enviroment:
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
Issue:
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?

Would leaving users logged in help with this scenario? I'm not sure we'd be able to stagger the users.
We do use folder redirection and it is hosted by the DC on the same HyperV server.

Are your synchronization settings set for logon or logoff.
When a user logs into a session, what is happening? How long does the logon process take?
One option is to use a tool such as cacti to collect resource usage using snmp data polling.
CPU, memory, network, etc.
Using that info you might be in a better position to see where the issue might be, you can use perfmon.
All your cms resideon the same separate disk, his might be where the issue is.

Log on during peak access (15 - 20 users in 20 minutes) takes about 3 minutes.
Log on normally is less than 20 seconds
I've been using Perfmon and have noticed the disk queue of between 8 and 12 during peak times. Would moving the DC to a separate disk help resolve this?

Thanks for keeping up with this and sorry for being so slow to get back. I will try rejigging the disks and get back to you with the results.

Worked like a charm.
It sounds that within a window of time all users login which might require a large amount of profile data import.
Do you alo use folder redirection? It might help reduce the amount of data that needs to be transferred at logon.
