[Python-ideas] Re: Fwd: Re: Experimenting with dict performance, and an immutable dict

Well, I simply forgot vectorcall.

I've done a test and it seems the speedup is about 25%. Unluckily, now I abandoned definitively the hope of a big big resize, but it seems I don't resize correctly, since now I have again an assert error on dk_usable.

What is the difference between dk_usable and USABLE_FRACTION?
