After optimization, tests on small ints (< 230) Currently only addition, subtraction, negation and ~ are a bit slower (< 5%). Most other operations are the same. Bitwise operators, //, %, and pow are faster. Converting to and from strings is a bit faster. pickle, marshal and json are faster. bm_nqueens is a bit slower. pystone is a bit faster. There are no performance regressions in other benchmarks. When I fix +,- and ~ I will reupload the patch.

Currently only addition, subtraction, negation and ~ are a bit slower (< 5%).

Most other operations are the same. Bitwise operators, //, %, ** and pow are faster.

Converting to and from strings is a bit faster. pickle, marshal and json are faster.

bm_nqueens is a bit slower. pystone is a bit faster. There are no performance regressions in other benchmarks.
