I ran "dbench -c client_oplocks.txt" (no sync) with 50 clients.
DBench-2.0 and client_oplocks.txt are from a debian sarge install.
The mount options are "noatime,nodiratime".
Tests run, again on /dev/loop0.
reiserfs: Throughput 5.92739 MB/sec 50 procs
ext3: Throughput 6.41044 MB/sec 50 procs
jfs: Throughput 5.92622 MB/sec 50 procs
jfs, case insensitive: Throughput 6.23852 MB/sec 50 procs
xfs: Throughput 6.08939 MB/sec 50 procs
reiser4: crash, after spawning around 10 of the 50 clients.

Hmm, "mkfs.reiser4 -q -o extent=extent40" does not help much for deletes.
As DELETE is horribly slow I guess its a bad interaction between
/dev/loop0 and reiser4, or it's the -cko3 kernel patch.
