I would be a bit hesitant to make such sweeping statements without at
least qualifying the usage the FS is destined for, and what options the
FS was mounted with. Benchmarks of ext3 vs ReiserFS have shown similar
performance of the two when mounted with equivalent options.

Run Mandrake (8.1 or later for XFS, 9.0 or later for ACLs on ext2/3, all
works out-the-box via samba). Mandrake 9.0 also has winbind support in
the install (if you need that).
Or, run RH, and get 3rd-party kernels from SGI for XFS, (or roll your own).

All of them use the draft posix ACLs.
Merged in-kernel with 2.4.19.

Depends of course on the file sizes ... very big files in sparse
directories will have a different effect ...

Even "official benchmarks" are difficult to interpret.
I have had issues with ReiserFS2.x, but we really need ACLs, so until
some distro supports ACLs on ReiserFS, it's not coming near my file
servers (mail/news/web maybe).
