I think there is more to it. I get decreasing (avg ~1-20%) bonnie
performance with 2.1.105 compaired to 2.0.3x but still 2.1.105 is
lightyears :) faster than 2.0 just in about anything - even the bare eye
can see it.

So basically what I wanted to say is: it is easy to do benchmarks but it
is quite tricky to interpret their results correctly.

Of course the results above would make perfect sense if there had been a
Adaptec driver update that would count for a 100% increase in
performance; which hasn't been the case for my ncr53c875.
