The attached program uncovers a two-fold performance regression in Python 2.5 with respect to Python 2.4. Below, the "element-wise" case goes from 2.5 seconds in 2.4 to about 4 in 2.5. Since that's a pretty serious increase, I thought I'd point it out. $ python2.5 periodic_test.py elwise 3.91989398003 collective 1.21577095985 $ python2.4 periodic_test.py elwise 2.50014710426 tuplewise 1.35589385033
