Hello, 

we are looking for better RDP permformance. Customer complains this things:

- scrolling in MS Word,  "typical RDP behaviar when not sitting in front of the mashine"
-usual tasks in their SQL based commercial software, switching Windows, Queries, etc..
- behavior of the typical power use  /  lots of open Windows in RDP Session

They have normal 1-2y year old windows 7 PCs, no thin clients.

What are your thoughts on this situation?  Do you have any Idea to imporve it?   thx in advance!

What about network connectivity? Which bandwith do you have for the virtual network interfaces? How are the clients connected to the network?
