I have a client who's interested in serving embedded videos (Flash/FLV) in their internal SharePoint portal to the thin client users on the Terminal Server. I suspect that the redraw rate is going to be slow, just as any "heavy" website like Yahoo or MSN is right now for thin client/Terminal Server users.
Question is, where is the bottleneck? Is it the GPU of the thin client, the Terminal Server, or a combination of both? I've ruled out network performance: there's CAT5e or CAT6 throughout the building with good high-quality 10/100/1000 switches and there's no performance issues for any of the workstations, just the thin client/Terminal Server users. The Terminal Server is running on Hyper-V with 8GB of RAM allocated, but even after-hours, with no other sessions, animated rendering/playback over RDP seems slow.
