I was very pleased to see the driver for my Adaptec 2130S controller get
into 6.2 release. TY Dev's! No using the binary anymore.
I do have a question on performance.
Using the binary driver on RC2 (same hardware, same unmodified GENERIC
kernel) I got these results...

Now using 6.2 Release running postmark I see these results:

Does anyone know what differences either in the driver (I was using
b11518) or OS itself that might account for the slightly decreased
performance?
I realize there may have been many changes that could effect the
results, just want to know if anything specific has been noted related
to this.
Don't get me wrong, the speed is fine not a complaint :)
Cheers,
Jeff
