Recently I had a power outage on a RaQ4r (512MB, 2 x 40Gb) which is running
the Qube3 OS and is fully patched with the latest kernel ... it took over 50
hours for RAID duplication to complete.

I have heard informally that the latest kernel may be the issue.

Perhaps the priority on RAID duplication has been reduced significantly such
that system performance remains close to normal.  If this is the case, I'd
prefer the system to be sluggish during RAID duplication and have it done
quickly.
