top, iotop or vmstat may give you some clues. It's worth noting that
xrdp uses VNC behind the scenes, which isn't the most CPU-efficient.
XDMCP may perform better, so both are worth looking into, particularly
if xrdp is performing poorly.
The places where I've been using xrdp have been in situations where
we've had no more than about 3 users simultaneously, and xrdp was chosen
because it makes life easier for the Windows users to access a box.
