More visibility for performance achievements would do good too.

Where are pypy's performance achievements *not* visible, but should be?

for example http://shootout.alioth.debian.org/ doesn't say which pypy version is used

Oh yes it does - http://shootout.alioth.debian.org/u32/compare.php?lang=pypy#about

what options, doesn't have performance figures for multithreaded/multicore

All the Python multiprocessing programs "Failed" with PyPy - http://shootout.alioth.debian.org/u32/measurements.php?lang=pypy

also benchmarks are kinda small, most of them are not docuemented, and I couldn't find any info if the same python code was used for cpython and pypy (both shootout and speed pypy) or interpreter-specific verions were used, that is each tweaked for best performance given the known tradeoffs for each implementation.

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.
