Since moving to the server 2008 our thin clients seem to be more laggy. The server is plenty beefy enough as well as the infrastructure. My suspension is that the new RDP for 2008 r2 is not playing well with our older Wyse S30 thin clients. I know they have a memory and performance issue, but I can't change then out right now.
The user is getting the screen paint issue instead of a quick refresh as before.
I know there was a lot more added to RDP to make it more multimedia friendly. However, the thin clients cannot handle the multimedia.
What settings can I look at to tune RDP for day to day screen activity ?
Attached are some screen shots of some RDP settings.
