Why is there no xrange function in Python3?
...only 30% slower. How did the OP get 2x as slow? Well, if I repeat the same tests with 32-bit Python, I get 1.58 vs. 3.12. So my guess is that this is yet another of those cases where 3.x has been optimized for 64-bit performance in ways that hurt 32-bit.
But does it really matter? Check this out, w...

Although with the design here you aren't forcing exclusive access so it's even possible you may be able to read the first byte, but no others (byte level locking).
