Every filesystem was best in at least one test. Filesystems
exhibit very different performance characteristics for some
workloads.
Results are similar to prior posting for 2.5.68. This time
reiserfs has notail, which helps some tests.
mount options
mount -t ext2 -o defaults,noatime /dev/sdc1 /fs1
mount -t ext3 -o defaults,noatime,data=writeback /dev/sdc1 /fs1
mount -t reiserfs -o defaults,noatime,notail /dev/sdc1 /fs1
mount -t jfs -o defaults,noatime /dev/sdc1 /fs1
mount -t xfs -o logbufs=8,logbsize=32768,noatime /dev/sdc1 /fs1
mkfs command
mke2fs -q /dev/sdc1
mke2fs -q -j -J size=400 /dev/sdc1
yes "y" | mkreiserfs /dev/sdc1 >/tmp/mkr.out 2>&1
jfs_mkfs -q /dev/sdc1
mkfs.xfs -l size=32768b -f /dev/sdc1
XFS mount/mkfs options came from the XFS FAQ and are very desireable
for these tests based on an earlier run without them. If anyone
knows better than default options for jfs, I'd like to hear.

Filesystems that did best on dbench 64 also did best on dbench 192.

One notable thing here is filesystems that did better in sequential block
writes had lower sequential re-writes.

bonnie++-1.02c creating 65536 small files
ext2 and ext3 have great numbers for sequential small file deletes.
reiserfs and jfs were faster at creating small files.
