Message 242260 - Python tracker

Throwing out sum, I'm seeing significant slowdown simply from xrange versus range:

taniyama:Desktop mdickinson$ python2 -m timeit -s 'x = xrange(3, 10**9, 3)' 'for e in x: pass'
10 loops, best of 3: 5.01 sec per loop
taniyama:Desktop mdickinson$ python3 -m timeit -s 'x = range(3, 10**9, 3)' 'for e in x: pass'
10 loops, best of 3: 8.62 sec per loop
