Hi, I checked this last year or so. OSA has fully caught up with the speed of hypersockets. Above that: with hypersockets, some processing is done on the CP, while with OSA that same processing is done by the OSA, so reducing CP utilization. There is one area where hypersockets have benefits over OSA, but I don't remember what it was, only that it was not applicable to our systems.
