Please contact me to get access to speed.python.org server. *Maybe* your process to run benchmarks is not reliable and you are getting "noise" in results. > On the other hand, meteor_contest shows 13% speedup. It uses set. > Other doesn't show significant performance changes. I recall that some benchmarks are unstable and depend a lot on how you run the benchmark, how Python is compiled (ex: PGO or not). IMHO it's fine if the overall performance result is "no significant change", as soon as we reduce the memory footprint. Victor -- Night gathers, and now my watch begins.
