I'm still (!) investigating the reasons why the benchmark call_simple (ok, let's be honest: the *micro*benchmark) gets different results for unknown reasons.

Try to define MCACHE_STATS in Objects/typeobject.c and observe the statistics from run to run. It might give some hints.

call_simple only uses regular functions, not methods, so the type cache should not have any effect on it. No?

Indeed, sorry for the mistake.

Antoine.
