I am trying to build a box that can handle streaming 2Gbps to disk for
sustained periods of time. I benchmarked a few different file systems
and wanted to share the results.
Software:
2.6.7 + my networking patches (my modules were not loaded, should not matter)
Fedora Core 2 fully up-to-date.
Latest 3w-9xxxx driver from their web site.
Hardware:
dual 2.8 Xeon, 1GB RAM, 40GB IDE OS hard drive
2 3ware 9500 controllers with 6 WD 7200 RPM 250GB SATA disks each
(Only one of the controllers was used for these tests, though initial
testing shows that when both are used, each runs as fast as when only
a single controller is used)
The 9500 controllers are set up for raid-0 with 64k stripes.
Motherboard: Tyan S2726 (Thunder i7501 Xtreme)
General test procedure:
mkfs.XXX /dev/sda1 (Default arguments only)
mount [sda1]
run tiobench
umount [sda1]
NOTE: I hear there is a patch to fix the crummy ext3 performance when using
multiple threads: I have not applied this patch. jfs and xfs both seem superior
performers, so I probably will not use ext3.
I am new to this type of thing, so suggestions are welcome. I can also run
other tests if someone has suggestions or results they would like to see.
Enjoy,
Ben

for large amounts of data, you should ensure that your application opens
the open using O_DIRECT.
i have no experience with 3ware controllers, but i have no problem
sustaining 400MB/s (4gbit/s) to a Fibre Channel-attached JBOD with an
in-house userspace-based application which maintains its own
userspace-based filesystem on raw partitions (/dev/sd[b-w]).
using 15K RPM disks i can sustain 400MB/s using just 6 disk spindles and
what amounts to predominantly sequential writes.
cheers,
lincoln.
