For an update-intensive setup, putting WAL on its own disk is definitely
your biggest win. You might then find it rewarding to fool with the
wal_sync_method and perhaps to bump up wal_buffers a little. A small
number of people have had luck with putting a nonzero commit_delay but
I have little faith in that.
