[lustre-discuss] LNET Self-test

I'm trying to use lnet selftest to evaluate network performance on a 
test setup (only two machines). Using e.g., iperf or Netpipe I've 
managed to demonstrate the bandwidth of the underlying 10 Gbits/s 
network (and typically you reach the expected bandwidth as the packet 
size increases).

How can I do the same using lnet selftest (i.e., verifying the bandwidth 
of the underlying hardware)? My initial thought was to increase the I/O 
size, but it seems the maximum size one can use is "--size=1M".
