How are you bunching your transactions? I mean how many updates per transaction? And have you tried moving WAL to separate disk for such a update heavy environment? Have you are tuned FSM to take care of dead tuples generated in vacuum? Are you running autovacuum daemon? All these things are almost a must for such update heavy environment..
