Hi Olivier,

I would recommend against this approach. Doing this will nullify the remote
desktop features of RDP (like bitmap caching and copying rectangles between

The result may look visually similar, but the information that remote
desktop servers hook into for efficient operation will be gone. The server
will be forced to do nothing but frequent and large brute-force image
comparisons, followed by encoding those large areas. This will be orders of
magnitude more intense than what would happen compared to typical
operations with respect to processing.

If you want the benchmark to be representative, you will need to script the
inputs of the user such that the applications running on the remote desktop
server are actually opened, used in a way typical of a user, etc. I don't
think there are any shortcuts around that which wouldn't also defeat the
