As Jakob mentioned, the slow down is quite possibly related to other
parts of the kernel.
I would really like to see speed comparisons for
2.2 no raid
2.4 no raid
where 2.3+raid didn't fit the pattern, before I looked too deeply.
Given the code at the moment, I am highly confident that linear, raid0
and raid1 should be just as fast in 2.4 as in 2.2.
There are some issues with raid5 that I am looking into. I don't
know that they affect speed much, though they might.
