SMP surely increases latencies (more synchronisation overhead), but the
tests you ran were also far to short for a thorough comparison. 2 us
worst-case is far too good, even on high end. Also 20 us on loaded SMP
boxes may not hold. Leave the test running for a longer period ("-T"
parameter, I think).
