I ran this patch against Unladen Swallow's slowspitfire template benchmark, which does more int->string conversions than any of our other benchmarks. When run against Python trunk r74737, I get these results: slowspitfire: Min: 0.888772 -> 0.867427: 2.46% faster Avg: 0.891857 -> 0.872461: 2.22% faster Significant (t=45.532127, a=0.95) (./perf.py -r -b slowspitfire ../a/python.exe ../b/python.exe) This was an idle MacBook Pro, OS X 10.5.8, Apple gcc 4.0.1, 2.4 GHz Core Duo. Other benchmarks benefit, but are only barely statistically significant.
