Performance may be better, I have no data on that, but I do know that
the Mac HFS starts to really choke when a directory begins to contain
hundreds of files. I have not had time to research things, but we
have seen a couple of cases where the Mac was disabled because it
could not seem to deal with the enormous number of files in a directory
(several hundred if I remember correctly).
