x86_64 aacraid help

[George Glover]

Hello,

I have a dual opteron machine, running a cross compiled test7 on a 32 bit
distro.  2 gigs of ram, irqbalanced, everything seems to run very well -
except for the aacraid driver.

It's an Adaptec 2200S, with 5 U320 drives connected (seperate channels
3/2).  Each drive seems to read ~70MB/s on it's own, both through the
aacraid driver and through the onboard fusion mpt controller.  Using
hardware raid 10 with aacraid reads ~100MB/s, it seems to go no faster -
regardless of raid levels.  However with software raid, I can nearly
double that (half on aacraid, half onboard)  I am not able to test it with
all drives using the onboard controller with software raid due to lack of
cables and not wanting to destroy the boot drive.

I am wondering if there is a magical go faster button that I'm missing?

Thank you,

George
