Based on a comment in this bugzilla thread, here are a couple of iozone + vmstat 1 tests run with:
/proc/sys/vm/dirty_expire_centisecs = 1000 (default is 3000)
/proc/sys/vm/dirty_ratio = 10 (default is 30)
but with no other tuning tweaks applied.
This change reduces the number of processes in 'b' state somewhat.
