Here's the revised vinum benchmarks using both rawio (the first batch)
and bonnie (the second).  In each case, the first 2 entries are
the seperate drives.  Then comes the vinum volume, testc.  I ran
striping at 128b, 256b, 512b and 1024b.

In all cases, vinum absolutly dies in the sequential write, at least in
my case.

Any comments?

first is the conf file.
