Somehow, this knowledge seems to have gotten lost in OSX. It might have some wonderful features, but a fast filesystem certainly is not one of them. People porting 'git' to OSX are discovering that the OS just takes a long time to stat all of the files in a tree (something you need to do to figure out if they've changed). Windows is thousands of times slower at this, and it appears that so is OSX.
The problem is that OS X isn't using any of the BSD filesystems. It's using the old creaky HFS-based stuff. Hopefully ZFS will finally correct that.
Perhaps there is some unwritten rule that to be popular, an OS must have a poorly performing filesystem.
VMS would be the counterexample. It was extremely popular for quite a while and had a good filesystem with features that we *still* don't have.
