You're right, no sense rehashing ancient history (and certainly
Voltaire has had years to contribute to openib SDP if it had an
interest in doing so).  However, just for the record, Libor later told
me that he felt the CPU usage numbers were likely inaccurate -- he
believed the difference was just coming from the fact that the
Voltaire SDP was spending more CPU in interrupt context, and my
measurement was missing that CPU time.
