How much memory does your test machine have? The performance will be
vastly different if there is enough RAM to hold the working set of
inodes and page cache (~20GB all up), and that could be one of the
factors contributing to the problems.
The above xfs_info output is from your 160GB SSD - what's the output
from the 1TB device?
Also, what phase do you see it hanging in? the random stat phase is
terribly slow on spinning disks, so if I can avoid that it woul dbe
nice....
Cheers,
Dave.
