Hi all, Very interesting discussion ... IIRC, timeit does some clever tricks like disabling the garbage collector, so for the first run of timeit, I suspect it does 10000 malloc (without associated free thus without the ability of recycling any of those buffers). On the second run, those buffer were allocated previously and kept by Python for re-use which could explain the faster run. This does not explain really the different between operating systems observed.
