Well, I've noticed that UFS seems to be considerably slower than HFS+.
It must be all that case-sensitive comparison that slows it down. :^)
Seriously though, what might be the reason for the speed difference? I
would have expected UFS to be more-or-less a direct copy of the BSD
filesystem and I haven't heard of speed problems on straight BSD
systems.
Well, that is the question. Apparently it is a fairly old version of
UFS (no soft updates). Also, I noticed I can't create files > 4 GB in
size. Also, there is the database file system issue where HFS+ can grab
directory structure info from a database rather than traversing the file
system. The bottom line is that I have yet to find any situation where
UFS is faster than HFS+. In any sort of file searching situation, HFS+
is just so much faster its silly.
My only concerns with HFS+ are the case issue, the potential lack of
performance in a multiprocessing situation where the file system gets
requests from many difference processes/threads, and the potential for
corruption without a journeling / soft updates scheme--it is possible to
avoid "fscks" (or their equivalents) for most versions of Unix these
days (IRIX, Linux, BSD (at least is goes on in the background after your
back up)).
I hate to beat this into the ground and I'll stop, but it is really the
only outstanding issue for me where we would adopt OS X in a wider
fashion (beyond desktops.) If they addressed this and ECC memory
support, well, I'd be so happy I'm not sure what I'd do.
