For the last day or so I have been running with a SheepShaver image I compiled with more aggressive optimizations. I don't have any timing numbers for you, I'm not quite sure what I could use as a benchmark.

In src/Unix/Makefile, for CFLAGS and CXXFLAGS I changed -O2 to -O3 -march=athlon64 -mtune=athlon64.

The size of the image went from 3895678 to 4290860 bytes, so it did something.

My system:

AMD64 3200+ (Winchester core).
1 GB RAM
Fedora Core 4 for x86_64
