I've had responsiveness issues when the viewing machine hasn't enough
CPU power to decode the screen data in real-time. A lot of power
seems to be needed, my PDA, a 416MHz ARM can't cope with any
compression at all, I have to limit vncviewer to copyrect and raw
encodings only. Encoding doesn't seem to need half as much CPU power.
I ran Xvnc on a headless server with a 400MHz AMD K6 with no issues
that I recall.

All that gear was using either TightVNC or the plain vnc-x.y.z.tar.gz
from RealVNC. When using Vine Server on a 466MHz Apple screen updates
are not really adequate,  while the mouse pointer lags if I use the
VNC server supplied with OS X Tiger on the same machine. x0vncserver
is a known problem server which I haven't used, IIRC it basically
works by taking screenshots continuously and sending those.
