Oh yes it does -

All the Python multiprocessing programs "Failed" with PyPy -

The full source code is shown for all the programs -

http://shootout.alioth.debian.org/u32/program.php?test=spectralnorm〈=pypy&id=6

http://shootout.alioth.debian.org/u32/program.php?test=spectralnorm〈=python&id=6

The GZip byte size is shown for each program, in this case 341 for
both programs.


Maybe the benchmarks game shows more information than you realize.
