They have translated the Python benchmarks of the Shootout site from Py2 to Py3 using 2to3:
http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=python3 It shows some "performance bugs" of Python3 itself (especially regarding the binary-trees benchmark, that was unexpected by me), and two points where 2to3 may be improved, for example after the translation this gives error: table=string.maketrans('ACBDGHK\nMNSRUTWVYacbdghkmnsrutwvy', 'TGVHCDM \nKNSYAAWBRTGVHCDMKNSYAAWBR')): Gives: TypeError: maketrans arguments must be bytes objects Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
