Here are some more NEC-2 running times for John Boyer's 1030 segment
benchmark. The DEC Alpha code was compiled with default settings. Sun
and Macintosh codes had -O optimization. The Mac code was compiled for
interupt checking at 1/6 second intervals, which is nicer to run than
with no interupts, but slows it down somewhat. It was compiled with the
Absoft F77 compiler. The Mac 8100/80 was one of the first PowerMac
models, and there are considerably faster ones available now. All
codes were compiled to run a maximum of 1200 segments. All gave an
input impedance of 138.64 - j164.46 ohms for each source.
