The funny thing was, after reinserting the original disk it did not

Then you can't compare RAID with no RAID effectively. You could compare the
speed of 2.2/2.4 RAID, and 2.2/2.4 no RAID, but comparisons across would

If it is slower, we look at the no-raid numbers.
If no-raid on 2.4 is slow than no-raid on 2.2, we say "oh dear, the
disc subsystem is slower on 2.4", and point the finger appropriately.

Hello
Since everyone is talking about disk benchmark and the results on
different kernel version I would like to ask a question about this.
I noticed when using bonnie that I could sometimes get very different
results ( 20%) using the same kernel and disks only that the second

And whats when /dev/sda failed? In this case LILO not

LILO's maintainer wrote to me, that the patch added to the
latest LILO, but the autoboot doesn't work. I get 0x80 or
similair errors.

Will this not influence the performance a lot since the head of
the disk has to walk all over the disk? Thus making comparisons
practically useless since you never know the state of fragmentation?
I think you've got it exactly right here.

Hi!
I've applied the raid-0.90-2.2.16-A0 patch to a 2.2.16 kernel and compiled
with multiple disk, autodetect, and raid1 support in kernel.
When I boot from this kernel, everything appear to be fine, except that no
devices (not even inactive ones) are listed in /proc/mdstat, although
17 matches
