I tried again, setting up RAID1 on 2 U320 drives, 15k, as described in

Now I find the speed to be too slow. Writing to a single file is kind of
okay: [everything/pwd is /mnt, which is a softraid drive, /dev/sd3f]

But a dump && restore of /usr is a tad sick:

I can see at times
that the data amount transfered is huge, at other times it is moving by
steps of 0.1-0.2 MB/s. Probably it is a problem of number of files, not
of size.
Any idea what to do to improve the performance?
In the generic "I restore/unpack a zillion files to a newfs:ed
partition", mount it async, which helps the "number of files"
issue, and if it fails in the middle, you will want to restart the
restore anyhow, so you just might newfs it again in that case.
