Before I get bashed by you sun3 owners out there. (I have 3 at work).
Let me clarify the above statements.

Because of the blitter and exec not being unix, X would run on a
plane 68k based amiga as fast if not faster than a sun3/50. The bits
certainly are moved and painted quicker, however X is not just blits.

Amiga exec is a very efficient low overhead multitasking system. I can't
say the same for unix. Since every operation that X does when dealing
with client<->server transactions requires task switching, it gets
more effective cpu time with a system that has less overhead when switching
tasks.

Also before I get flamed for being antiunix, nothing is further from
the truth. I've ported several early versions of unix to a 68k based
machine in a previous life.

It is also quite a bit of nonblitting code which is slower on a 7.2mhz
68000 than a 15mhz 68020.

So some operations will be faster, some will be the same speed, and some
will be slower. Depends on the resources needed.

Although I do contract work for Amiga-LosGatos, my opinions probably
don't represent those of Commodore or its management or its engineers,
but I think the world would be a better place if they did.
