HA! 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). A reply path to Peter is: Usenet: {allegra|decvax}!ucbvax!Deutsch@Xerox Arpanet/CSNet: Deutsch@Xerox.Arpa If anyone has troubles, I'll try to help (mdr@uw-june) Mike Rutenberg Xerox Parc (415)494-4379]]
