index-pack usage of mmap() is unacceptably slower on many OSes other than Linux
It was reported by Randal L. Schwartz <> that indexing the Linux repository ~150MB pack takes about an hour on OS x while it's a minute on Linux. It seems that the OS X mmap() implementation is more than 2 orders of magnitude slower than the Linux one. Linus proposed a patch replacing mmap() with pread() bringing index-pack performance on OS X in line with the Linux one. The performances on Linux also improved by a small margin.
