"Lucas Hofman > This machine benchmarks at 38167.9 pystones/second Pystone is an abyssmally bad benchmark for comparing the relative speeds of different versions of python (it nets out all eval loop improvements and it exercises only a microscopic portion of the language).
I would be interested in seeing other people's comparitive results for pybench, test_decimal, and parrotbench. To run test_decimal.py, you first have to copy Lib/test/decimal.py into Py2.3's lib directory. On an old PentiumIII running WinMe, I get 48.940 sec in Py2.3 and 44.820 sec in Py2.4, a 8.4% improvement. For pybench, I get 7418.90ms in Py2.3 and 6320.07 ms in Py2.4, a 14.8% improvement. For parrotbench, I get 54.517 seconds in Py2.3 and 45.009 seconds in Py2.4, a 17.4% improvement. It is also interesting to time specific features not covered by the above benchmarks. For example, list comprehensions got a nice 60% boost on my machine: C:\py24\Lib>\python23\python timeit.py -r9 "[i for i in xrange(1000)]" 100 loops, best of 9: 1.11 msec per loop C:\py24\Lib>\python24\python timeit.py -r9 "[i for i in xrange(1000)]" 1000 loops, best of 9: 417 usec per loop Raymond Hettinger -- http://mail.python.org/mailman/listinfo/python-list
