Subject: Re: 3Ware 9500S-12 RAID controller -- poor performance
Date: Fri, 07 Oct 2005 22:35:49 +0100 [thread overview]
Message-ID: <4346EA35.90700@uklinux.net> (raw)
You might be interested in trying a small tool I wrote to perform some
parallel write tests on different linux filesystems.
http://marc.theaimsgroup.com/?l=linux-kernel&m=107661735307313&w=2
At the time that I wrote the tool, 18 months ago, both ext3 and
reiserfsV3 performed fairly badly at handling concurrent writes and only
JFS and XFS excelled. Since then I believe the ext3 performance has been
greatly improved due to the block reservation scheme added in 2.6.10.
AFAIK the reiserfs performance is only addressed in reiserfsV4.
The test code is fairly trivial and could be easily adapted to simulate
other workloads (like a web server) to help to optimise your filesystem
and driver performance.
tiobench provides another threaded IO test http://tiobench.sourceforge.net/
