If you think that X-Window's slowness is due to it having been written in C,
you are sadly mistaken.  The reason it's slow is that it has to convert each
call to a network packet, and send it over the network (or socket).

First of all, mostly high level commands get sent over the network.  The
communications performance is bad, but not as bad as you imply.  On a system
which doesn't use a network (client and server are all on the same machine)
sockets surely slow you down.  Why?  That part of the operating system is
written in C! :-)

Seriously, though, scrolling and redrawing are server operations, even these
operations take a fast machine to work reasonably well.  On a SPARC this
works okay, on a Sun-3, well you can go take a coffee break.  I'd hate to see
it on an Apple IIgs, even with a TWGS.
