The problem with dbench is that the core VFS can end up being the
bottleneck.  OTOH, it's very easy to run.  What would be great if you
could try using the Flexible File System Benchmark (FFSB), which is
what Eric and Steve used:

     http://btrfs.boxacle.net/

It's a bit more work to set it up, though.
