This is a collection of benchmark runs with the FFSB test suite. The
results are comparable to other raid results on the boxacle server. 

The latest results can be found at:

I added XFS without barriers and EXT3 with barriers into the mix since
my last data set. 

In general things look about the same.  There are a few cases where ext4
with barriers (default) has gotten better but ext4 without barriers has
gotten worse.
