Optimizations

The net result of the 3.0 generalizations is that Python 3.0 runs the pystone benchmark around 33% slower than Python 2.5. There’s room for improvement; we expect to be optimizing string and integer operations significantly before the final 3.0 release!

Performance

The net result of the 3.0 generalizations is that Python 3.0 runs the pystone benchmark around 10% slower than Python 2.5. Most likely the biggest cause is the removal of special-casing for small integers. There’s room for improvement, but it will happen after 3.0 is released!

恩 好好优化 应该还是有不少提升空间的

我想起了别人blog上的一句话^_^
