Benchmark of 1000 times "python -c ''"

Python 3.4dev with all my experimental patches: Avg: 0.705161 -> 0.443613: 1.59x faster 2.7 -> 3.4dev: Avg: 0.316177 -> 0.669330: 2.12x slower 2.7 -> 3.4dev with all my patches: Avg: 0.314879 -> 0.449556: 1.43x slower http://pastebin.com/NFrpa7Jh Ain't bad! The benchmarks were conducted on a fast 8 core machine with SSD.

This seems promising. What OS are you using? On an older Linux server with old-style HD's, the difference between 2.7 and 3.2 is much larger for me:

Avg: 0.0312 -> 0.1422: 4.56x slower

(In this case, I think it might be more useful to report as 0.11s faster, though.)

Cheers,

Dirkjan
