Is there any relationship between malloc and the page size (Linux, Windows, Mac)? Can this relationship be exploited for run-time systems that provide memory management themselves (e.g. GC, object allocation, ...)? My guess is that an allocation granularity of size of page - malloc metadata might give better performance (cache, swapping), but I do not have evidence for that.

Memory allocation does not consume any of the page for metadata – stark Oct 09 '14 at 15:13

@stark Are you sure? Keep in mind that we're talking `malloc`, not `mmap`. I vaguely recall a malloc implementation that keeps its metadata segregated, but AFAIK many others put it in the allocation. – Oct 09 '14 at 15:19
