Subject[benchmarks] various filesystems on 2.5.68
From

Filesystem benchmarks on 2.5.68 for 5 filesystem types.
Same LUN (RAID0) and partition used for each filesystem.
QLogic 2200 Fibre channel.
Quad P3 700 Xeon with 3.75 GB RAM.
System not rebooted between filesystem runs.

Every filesystem was best in at least one test. Filesystems
exhibit very different performance characteristics for some
workloads.

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 /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

Very recent version of xfsprogs/jfsutils/reiserfsprogs/e2fsprogs.

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 or another fs, I'd like
to hear.

Htree in ext3 helps a lot in the bonnie++ small files test.

tiobench-0.3.3 average of 3 runs.
Unit information
================
File size = 8192 megabytes
Blk Size = 4096 bytes
Rate = megabytes per second
CPU% = percentage of CPU used during the test
Latency = milliseconds
Lat% = percent of requests that took longer than X seconds
CPU Eff = Rate divided by CPU% - throughput per cpu load

ext3 on tiobench sequential read and write tests degrade much more than other
filesystems as thread count increases.
