siod-v1.3 now in comp.sources.unix

[gjc@bu-it.BU.EDU (George J. Carrette)]

Siod went out on comp.sources.unix sometime this week.
Here are some benchmark results for a random selection of
machines I happened to have handy. Not very favorable to DEC machines
compared with most other benchmarks. Someone on this list said they had
IBM 3090 timings?

Unix compilations done with the -O flag. All 68020 machines
with -f68881. Heap size of 120000 used. Timing done with standard-fib
procedure in siod.scm using SIOD Version 1.3 (which is slightly slower
than earlier versions). AMIGA 500 FIB(20) time is extrapolated from
the FIB(15) time.
