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.
