Folks,
In addition to the vinum vs. DPT SmartRAID IV benchmarking that I
had done, I've also started doing filesystem/OS-level benchmarking
with a program called "postmark" that Network Appliance wrote to show
off the performance of their NetApp Filers.
See <http://www.netapp.com/tech_library/3022.html> for the paper
from NetApp that shows the performance of their filers against
various other systems, and it also includes a link to the page where
you can get the source code. The source code compiled and is running
just fine for me under FreeBSD 3.3-RC. Not a single hitch.
Their best results on an F630 with 1000 files and 50,000
transactions were 253 transactions per second, 799.91 KBytes/sec
read, and 817.89 KBytes/sec written.
I just ran this same test on an old PPro 200Mhz system with 128MB
of RAM and softupdates on a Western Digital Enterprise 4.5GB hard
drive. I got 282 transactions per second, 869.09 KBytes read per
second, and 888.63 KBytes written per second! This ancient machine
with a single slow hard drive, but running FreeBSD 3.3-RC with
softupdates beats their *expensive* NFS file server!!!
I'm going to run this on some other machines, including the same
machine and disk without softupdates, FreeBSD 3.2-RELEASE on a
dual-processor PIII @ 450Mhz without softupdates on both the single
Western Digital boot disk and on the external DPT SmartRAID IV
striped array of four IBM 10kRPM UltraStar 9LZX drives, a single
processor Pentium III @ 450Mhz running Linux 2.9 on the internal hard
drive and on the external DPT SmartRAID V controlled striped array of
five Quantum Fireball 7200RPM 9GB drives (both mounted async and
sync), and any other machines I can get my hands on. I think this is
going to be fun!
