Interesting results!

Another data point for the benchmarks that would be interesting is memory consumption of the python process during the runs.

In 3.3 a reasonable place to gather this would be to add a callback to the new gc.callbacks and save a snapshot of the process's memory usage before every collection to gather peak, average and median usage over the life of the process.  2.7 doesn't have this feature but there is a backport of this to 2.7 in the bugtracker.

I guess I should join speed@ :)


There is already support in perf.py to track memory:

-m, --track_memory    Track memory usage. This only works on Linux.
