Hercules performance

Hardware is Intel 3.06 Ghz, 1 Gb of DDR RAM, 120Gb hard drive.
Currently running Hercules under WinXP/Cygwin. Would I get better
performance if I ran Hercules under a 686 based Linux rather than
WinXP/Cygwin?

Probably not. There have been more than a few folks running comparison
tests, and they all show performance within the limits of measurement error
between Windows and Linux versions - and they don't all agree on which is
even that little bit faster.

You've got a nice box there. How fast will your system run in a tight loop?
I'd expect it to break 40 MIPS. Is hyperthreading present and enabled? Can
you enable/disable it? If so, how much difference does it make?

I haven't done the test between HT and non-HT yet. Also, which
Hercules disk image performs better, compressed or non-compressed?
