This sounds like an issue with your mouse driver or video driver in
XFree86 - it's not something I've ever seen. Certainly worth
complaining about until someone helps get it fixed!

I've only really noticed this when using the Vesa driver or other
chipsets that don't have proper XFree support for graphics acceleration.
(Other exceptions include dragging a window over something like Mozilla
which takes forever and a day to redraw itself; and also dragging a
window from one monitor to another in Xinerama mode, which I /suspect/
is slow because my graphics card either doesn't have some kind of
accelerated support for this, or because XFree86 isn't taking advantage
of it. The latter I don't really care much about, and I suspect the
former needs to be fixed by the Mozilla people not the XFree86 people.)

At least 10kbit? It's incredibly bad at 64kbit! :-) This is, I think,
a case of "broken as designed". (It works just fine over 10Mbit
ethernet... :-P) I don't believe it's pixel data that's being sent
over the network - X is higher level than that - and in fact you can get
better performance over a slow connection using something like VNC which
/does/ send raw pixel data over the network.
