Hi,
in order to tune raid performance I did some benchmarks with and without the
stripe queue patches. 2.6.22 is only for comparison to rule out other
effects, e.g. the new scheduler, etc.
It seems there is a regression with these patch regarding the re-write
performance, as you can see its

Good evening,
I hate to be a noob, but my system is dying (I think it's a bad
motherboard) so I wanted to get this email out before the system
died again.
I've got 2 different RAID-1 devices (md0 and md1). md0 uses
the on-board IDE controller and md1 has two SATA drives
each is attached to a

Thanks for the extra details.
I still cannot manage to reproduce it which is frustrating, but I
think I can fix your array for you.
Get the source for mdadm 2.6.3, apply the following patch, then use
mdadm -A /dev/md0 --update=this /dev/sd[abcde]
that should re-write the part of the

In my opinion, one
of ways to increase raid5 performance may be to change STRIPE_SIZE to
to a bigger value. It is now equal to PAGE_SIZE. But we can't just
change it simply, some other codes must be modified. I havn't tried,:).
Maybe Neil can
