Also, Basilisk II's 680x0 emulation is waaaaaay faster than
SheepShaver running Apple's 68K emulation. Sometimes it's even faster
than a PowerPC version of the same program running on SheepShaver.

Here are some benchmarks for my Mandelbrot program, showing
floating-point performance of IEEE 32-bit and 64-bit floating-point
add/subtract/multiply. All are on the same 2.2 GHz Nehalem Core i7:

BasiliskII's JIT compiler running a 68K native version of the program:
  Single precision: 227 MFLOPs/sec
  Double precision: 55.2 MFLOPs/sec

SheepShaver running a PowerPC native version of the app:
  Single precision: 148 MFLOPs/sec
  Double precision: 164 MFLOPs/sec

SheepShaver's JIT compiler running Apple's 68K emulator, running the
68K version of the program and using SANE library for floating point:
  Single precision: 0.74 MFLOPs/sec
  Double precision: 0.69 MFLOPs/sec
