Infiniband shall give lower latency & CPU utilization and better 
real-world throughput, so that's probably better Lnet-wise.

But Infiniband gears are more expensive so if taking budget into 
account, 100G Ethernet may work good-enough allowing saved cost be used 
to upgrade other parts of the system.
