With a Delta 66 you don't need a small sample size which helps with the
first part.  I have to disagree with the ext2 part.  Check out Mark
Knecht's filesystem tests on my page
(http://myweb.cableone.net/eviltwin69/Arcana.html).  He used Benno's
latency test for his comparison.  I use Reiser and I get fewer xruns
than I did with ext2 or ext3.
