Ok, I tried playing a little bit more, and switching to the DeadLine scheduler really helped things. I have topped around 73% IOWait, but it never bogged the whole box down. I still need to do definitive testing (via tests already in the bug report), but this seems to have helped. Not sure which problem this relates to in this bug though; I'm guessing the scheduler one.
