I don't think it matters. Here's a quick comparison between 2.5 and
3.0 on a relatively small 17 meg file:
C:\>c:\Python30\python -m timeit -n 1
"open('C:\\work\\temp\\bppd_vsub.csv', 'rb').read()"
1 loops, best of 3: 36.8 sec per loop
C:\>c:\Python25\python -m timeit -n 1
"open('C:\\work\\temp\\bppd_vsub.csv', 'rb').read()"
1 loops, best of 3: 33 msec per loop
That's 3 orders of magnitude slower on python3.0!
