I should explain that this machine is being accessed by approximately
10-20 users writing and reading to the same large array (pic here:
http://dataw0lf.phonese.cx/comments.php?607). Most of these users are
running instances of Boeing's Softplotter photogrammetry application off
the same machine's X server, and the files they are accessing can range
from 1 to 100 raw TIFF images of 1 to 2 gigs. So the time is actually
quite phenomenal. AdvFS is quite a powerful filesystem.
Here's the load average on the machine, before I ran the test:
11:24 up 332 days, 1:53, 12 users, load average: 2.88, 2.93, 3.04
