Hi,
Out of interest I ran the taskspeed.py test on a range of Stackless
Python versions with the following OS / hardware:
Windows XP Pro x64. AMD Turion 64 / ML-34.
Here are the results:
2.3.3 Stackless 3.1b3 050929 (#51, Aug 14 2006, 11:58:33) [MSC v.1310
32 bit (Intel)]
10000000 frame switches took 4.73312 seconds, rate = 2112773/s
10000000 frame softswitches took 1.84762 seconds, rate = 5412381/s
10000000 cfunction calls took 2.67088 seconds, rate = 3744083/s
