Apple's UFS implementation is a big-endian variant inherited from a mixture of Sun and NEXTSTEP code back in the late 80's and early 90's, later seasoned by BSD-4.4Lite. The tradeoffs between HFS+ and UFS are sufficiently complex that neither is a clear winner for general purpose uses, although UFS tends to do well for lots and lots of little files-- think a squid cache, maildir mail spool, tradspool INN layout of Usenet articles; HFS+ by contrast is Unicode-aware and thus supports international filenames sanely, and the B-tree data structure handles volume-wide operations more efficiently, with a lot less head motion, than the highly-recursive tree traversal that UFS mandates. If you're setting up very large filesystems, greater than 10 terabytes, the Xsan product is a solution that even a non-expert admin can get working without fighting too hard. I haven't had the hardware to try to configure a comparably large filesystem using UFS under FreeBSD, but anecdotes suggest that going above either 2TB or 4TB constitutes sailing into unknown waters... -- -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
