> Should I make a patch? -1. This could consume quite a lot of memory, and I doubt that the speed improvement would be significant. Instead, I would check whether performance could be improved by just dropping the freelist. Looking at the code, I see that it performs a realloc (!) of the frame object if the one it found is too small. That surely must be expensive, and should be replaced with a free/malloc pair instead.
I'd be curious to see whether malloc on today's systems is still so slow as to justify a free list. If it is, I would propose to create multiple free lists per size classes, e.g. for frames with 10, 20, 30, etc. variables, rather than having free lists per code object.
