performance of nvidia onboard raid1 vs. gmirror

[Ken Gunderson]

Greets All:

Sent this to fbsd-geom a few days back but didn't get any response so
thought I'd risking your wrath and reposting here since I am
specifically interested in fbsd-amd64 context. I shot an inquiry to the
gmail address of the sunfire x2100 poster to the amd64- hardware page
but didn't get any reply there either.  Anyhow, here goes....

I've been using gmirror for quite some while now and it's worked well
for me.  However, I was curious how it performed in comparison
to nVidia onboard raid offerings on various nforce boards that FreeBSD
now supports.

For example, the fbsd-adm64 mainboard support page links to this dmesg
for a Sun X2100:

The part piquing my curiosity being:

"The onboard raid is fully functional to me (WD Raptors instead of the
stock seagate disks). I made a bonnie test which showed imressive
perfomance, but slightly hight CPU usage."

Is anyone aware of any benchmarks comparing the nvidia raid1 to
gmirror?  Or have any additional insights?  I don't have a machine free
I can test on at the moment but might in next week or two if anyone else
is interested.
