Assuming that you are using the right settings, see:
http://xpra.org/trac/wiki/Encodings
(usually means using lz4+rgb on a LAN, or h264 otherwise)
Encoding is almost always CPU bound on the server side, rarely an issue 
client side.
(having opengl rendering client side helps too)
Handling fullscreen at resolutions higher than 1080p is a different 
problem, which we will try to deal with in future releases.
