Grant,

> Could you run the ibv_pingpong test and report what that gets?

Using: ibv_rc_pingpong --size=1048576 I am seeing 942 Mbytes per sec.

As I said previously, we have an internal application that sees ~950 
MBytes per sec using RDMA Write. It looks like ibv_rc_pingpong is using 
send receive  and not RDMA. Perhaps someone (Roland) has an RDMA Read 
test they can point me to?

Thanks,

Galen
