Deadline was much faster. Using sysbench:

So... FYI. I rebooted with elevator=deadline as a kernel param.
db2:~# cat /sys/block/sda/queue/scheduler noop anticipatory [deadline] cfq
(which I assume means I'm now running deadline. Is there any other way to find out?)
And no performance diff. Note that you're benchmarks only show a 20M addition overhead. We're about 60x too slow for these drives so I'm not sure what could be going on here :-/
