I noticed that Linux SIMH is about twice as fast on OS X.
KUHAVX got about 12 VUPS when running natively on a Core i5 iMac, 24 when in a Linux VM on
the same hardware. Pretty weird.
Weird indeed. Maybe 64 bit vs. 32 bit binary? Or some weird optimizations when building
simh for Linux?
After all, the Linux virtual machine runs rather native, so the slow down in that step is
pretty minimal.
