Unladen Swallow 2009Q3 ↦

The latest milestone in Google’s laudable effort to speed Python is out. The previous milestone, 2009Q2, introduced a massive increase in memory usage when compared to the standard CPython implementation which has been tamed considerably in this milestone (though not eliminated completely). Q2’s ten fold increase is now down to only a two or three fold increase in memory usage. Overall performance has increased 15–70%, depending on the benchmark.
