[issue1087418] long int bitwise ops speedup (patch included)

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

The type is an important performance factor but most uses of it are for
small ints (< 2**32 or 2**64), so your approach wouldn't make much of a
difference.
Besides, there are already some improvements in the py3k branch (for
example, longs now use 30-bit "digits" on 64-bit systems).

Yes, they are. As a result, calculations on small ints have become a bit
slower.
