XFS performance
Hi,
I just have tested performance of xfs and ext3 on my new Dell PowerEdge 1550
RERC3/DLC RAID with 3 36Gb disks in RAID5, Dual PIII 1000. Running linux
slackware 8.0 glibc 2.2.5 with linux 2.4.17 from cvs tree.
Mkfs options -l size=8192b, partition size 30Gb
mount options logbufs=4,osyncisdsync
Bonnie++ XFS results:

And ext3 results:

As I see ext3 is match faster. Why??
May be I should use another mount options or mkfs options to have better
performance?
Thank you.
