Here's a pybench comparison, on OS X 10.5/Core 2 Duo/gcc 4.0.1 (32-bit non-debug build of the py3k branch). I got this by doing: [create clean build of py3k branch] dickinsm$ ./python.exe Tools/pybench/pybench.py -f bench_unpatched [apply 30bit patch and rebuild] dickinsm$ ./python.exe Tools/pybench/pybench.py -c bench_unpatched Highlights: SimpleLongArithmetic: around 10% faster. SimpleComplexArithmetic: around 16% slower! CompareFloatsIntegers: around 20% slower. I'll investigate the slowdowns.

[create clean build of py3k branch]
dickinsm$ ./python.exe Tools/pybench/pybench.py -f bench_unpatched
[apply 30bit patch and rebuild]
dickinsm$ ./python.exe Tools/pybench/pybench.py -c bench_unpatched

Highlights: SimpleLongArithmetic: around 10% faster.
            SimpleComplexArithmetic: around 16% slower!
            CompareFloatsIntegers: around 20% slower.

I'll investigate the slowdowns.
