Do you have some evidence for this?

I know it's the case for ffs or ext2 (in its default configuration), but HFS+ uses a tree structure for directory contents, so in testing I did in the past, there isn't much of a reason for making a big directory hierarchy.

Back in the 10.1 days, I did some testing with many items in a directory (over 10,000, but I don't recall what the maximum number I tested with was) with no noticeable performance difference (except with the Finder, which choked).


The files dont live on HFS+. In any case, the current load time of http://distfiles.macports.org/ is pretty good evidence.
