Turns out write performance is also slow! The program below takes
3 seconds on python 2.5 17 seconds on python 3.0 yes, 17 seconds! tested many times in various order. I believe the slowdowns are not constant (3x) but some sort of nonlinear function (quadratic?) play with the N to see it. =================================== import time start = time.time() N = 10**6 fp = open('testfile.txt', 'wt') for n in range(N): fp.write( '%s\n' % n ) fp.close() end = time.time() print (end-start) -- http://mail.python.org/mailman/listinfo/python-list
