Do you have a happy dbench > command line or similar that you would like to see run? 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://free.linux.hp.com/~enw/ext4/2.6.34/ http://btrfs.boxacle.net/ It's a bit more work to set it up, though. - Ted
