Cross-OS benchmarks...

[Charles Huber]

Here's the hardware:
8x WD15EADS 1.5TB drives
LSI SAS3081E-R SAS card in the 'close' 8x PCIe slot
Intel S3210SHLC motherboard
2.66GHz Xeon (BX80580X3330) processor
8GB DDR2-800 ECC memory

Debian 5.0 (w/zfs-fuse 0.6.0), FreeBSD 8.0-RELEASE, and OpenSolaris
2009.06 are installed. I had to make the array (8-drive raidz2) in
FreeBSD since at v13 it had the lowest zpool version of the three.


At this point I've only done some simple iozone's (attached). Sorry
for the truncated OpenSolaris run, got a bit impatient and didn't want
to wait another two hours to be told again that the WD15EADS's are
only good for ~80 IOPS :)

I'm planning on doing another iozone run with expanded record size
selection, though without the random read/writes.

Are there any other reasonably quick (<30 min.) iozone options or
other benchmarks that people might like to see? Nothing is on the
zpool yet, so I can switch the layout around too.

Thanks!

I typically run 'iozone -I -a -s 256M -r 4k -r 64k -r 512k -i 0 -i 1 -
i 2'?

-I (O_DIRECT) eliminates a lot of caching effects you are seeing.

Thanks,

More iozone runs attached. Still on the 8-drive raidz2.

iozone doesn't seem to do O_DIRECT on FreeBSD or OpenSolaris :/

Would you be so kind as to post these on the website? Register and I'll make
you a manager so you can create a folder performance and post them there.

[Charles Huber]

Sure! Would that go under the Issue tracker somewhere or a new top-level tab?

I'd advise you to create a new toplevel folder (call it infobase or
wiki?) and put stuff inside that folder. Don't forget to publish posted
files and the folder itself to have it be visible to nonlogged users.
Let me know if you need manager privileges to do this.

[Charles Huber]

Alrighty, I'll give that shot. I registered as "genpfault" on the site.

I have made you a manager. You'll see new UI elements after a refresh.
