We've never been able to get very good IPoIB throughput on these systems
(dual 3.0 GHz EMT64 CPUs).  SDP performance seems very good, though.
 
We're using LionCub Rev C HCAs.
 
To summarize:
 
min SDP latency: 26 usec
max SDP throughput: 7.2 Gb/sec
min IPoIB latency: 32 usec
max IPoIB throughput: 1.7 Gb/sec
 
Scott
