Jay,

Aside from the really odd issue of wanting to run Squeak on a 68k
Simulator... :-)

Nah. I'd say for one thing it's poor x86 code to begin with. There are a few
hacks that make a huge difference - for example, my (Win98) 700MHz P3 gives
me:

'56,239,015 bytecodes/sec; 1,677,593 sends/sec'

Note that the send speed scales with the machine speed but that the byte
codes are actually faster on my (slower) machine. Somebody ought to look at
that gnuify script and find out what's broken on Linux. There's a factor of
two lurking in byte code speed right around the next corner.

Cheers,
