If you don't run noatime, you'll generate significant writes, depending on access type as I recall, and there's other things going on...
I'm still going to run with "not significantly faster". :)
I would tend to agree, given the original premise of random I/O, since most of the time the controller will just be waiting for seek completes, no matter how deep the tag queue is. Having more controllers should help if there is significant sequential I/O, since you should be able to get multiple parallel streams going. With WAFL, this should happen a lot for writes, so it is probably a modest win overall.
