Just to correct some errors of fact: according to the published 
benchmarks, using the sum of the times for the macro-benchmarks
as the overall performance figure, Smalltalk-80 runs at 
approximately 15-20K bytecodes/second on the Lisa, 30-40K on the
Dolphin, about the same speed on the Sun Microsystems
workstation (68010) under the U.C. Berkeley implementation (BS),
70K on the Magnolia (this is a private communication, better than
the published number), 100K on the experimental 68010
implementation at PARC (as reported at 1984 POPL), and
250K-300K on the Dorado.  The Berkeley and PARC 68010
implementations use 32-bit pointers; all the rest use 16-bit
pointers.  As of this writing, only BS has a working, usable
virtual memory system (it runs under 4.2bsd): I don't know
whether its published performance figure is CPU time or real time.

[[Note: Net.lang.st80 is now somewhat (that's me!) linked with
a Smalltalk-80 interest list on the Arpanet.  Posting to Usenet
will make it and the other way may make it (snicker!).  If
you've seen this before, I'm sorry (I don't think it made it
out of uw-june before it went down for 4.2).

If anyone has troubles, I'll try to help  (mdr@uw-june)
