vnc vs freeNX?

[James Weatherall]

Felix,

You're using a very old release of VNC, which would explain why you see poor
performance over extremely slow networks.

VNC doesn't "stream raw bitmap data" (unless you explicitly configure it
to...), and your assumption that an X11-based protocol will always be faster
is not valid.

Cheers,

Wez @ RealVNC Ltd.
