Agreed. I did see that behavior with older kernels.

Yes, I'm going to rebuild my RAID setup so that I have mirrored
SCSI partitions for my external log (in the same SCSI disks where the
RAID5 array lives, so the performance won't be optimal either, but I
guess it's the best single disk failure protected setup I can manage with
the hw I have).
I'll post my benchmarks as soon as I get the new setup running.
