Oh, this was new to me. But the setting didn't change anything. I can
copy one large file between the xfs and ext3 disk (both ways), and I get
speeds between 160 and 200 MB/s. But unpacking the kernel source takes
between 5 and 10 minutes on the xfs disk, and a mere 15 seconds on the
ext3... (and it also used to take between 5 and 10 minutes when I had
xfs on the raid0, so it doesn't seem to be hardware related...)

If anyone has anything more I can try before I do the lengthy process of
backup 1TB, reformat and restore...

Thanks :)
