On the PEP371 it says "All benchmarks were run using the following: Python 2.5.2 compiled on Gentoo Linux (kernel 2.6.18.6)" On my iMac 2.3Ghz dualcore. python 2.6 iTaulu:src torppa$ python run_benchmarks.py empty_func.py Importing empty_func Starting tests ... non_threaded (1 iters) 0.000002 seconds threaded (1 threads) 0.000227 seconds processes (1 procs) 0.002367 seconds non_threaded (2 iters) 0.000003 seconds threaded (2 threads) 0.000406 seconds processes (2 procs) 0.003465 seconds non_threaded (4 iters) 0.000004 seconds threaded (4 threads) 0.000786 seconds processes (4 procs) 0.006430 seconds non_threaded (8 iters) 0.000006 seconds threaded (8 threads) 0.001618 seconds processes (8 procs) 0.012841 seconds With python2.5 and pyProcessing-0.52 iTaulu:src torppa$ python2.5 run_benchmarks.py empty_func.py Importing empty_func Starting tests ... non_threaded (1 iters) 0.000003 seconds threaded (1 threads) 0.000143 seconds processes (1 procs) 0.002794 seconds non_threaded (2 iters) 0.000004 seconds threaded (2 threads) 0.000277 seconds processes (2 procs) 0.004046 seconds non_threaded (4 iters) 0.000005 seconds threaded (4 threads) 0.000598 seconds processes (4 procs) 0.007816 seconds non_threaded (8 iters) 0.000008 seconds threaded (8 threads) 0.001173 seconds processes (8 procs) 0.015504 seconds -- Jarkko Torppa, Elisa -- http://mail.python.org/mailman/listinfo/python-list
