Subject: [BENCHMARKS] 2.5.70 for 4 filesystems
Date: Sat, 31 May 2003 12:33:52 -0400 [thread overview]
Message-ID: <20030531163339.GA9426@rushmore> (raw)
Summary: jfs had unkillable dbench processes. I've seen dbench have
some processes not exit (various filesystems) in recent 2.5.x.
This was the first time they were unkillable.
Every filesystem was best in at least one test. Filesystems
exhibit very different performance characteristics for some
workloads. For these benchmarks, xfs with non-default mkfs/mount
options is impressive.
Same LUN (hardware RAID 0) 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.
mkfs commands
mke2fs -q /dev/sdc1
mke2fs -q -j -J size=400 /dev/sdc1
yes "y" | mkreiserfs /dev/sdc1 >/tmp/mkr.out 2>&1
mkfs.xfs -l size=32768b -f /dev/sdc1
mount commands
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 xfs -o logbufs=8,logbsize=32768,noatime /dev/sdc1 /fs1

bonnie++-1.02c with 65536 small files
reiserfs and xfs create small files faster than ext2 and ext3
but are slower at deleting them.

Random small file create performance is similar to sequential.
Random small file deletes are a lot slower on ext2/ext3
compared to sequential deletes.
