NetBSD's is 139MiB/s, FreeBSD, OpenBSD, DragonFlyBSD have very similar code as NetBSD and are probably identical, illumos's is 141MiB/s without an argument, 100MiB/s with. OS X just uses an old NetBSD version similar to OpenBSD's, MINIX uses NetBSD's, BusyBox's is 107MiB/s, Ultrix's (3.1) is 139 MiB/s, COHERENT's is 141MiB/s.
