I don't think this targets multiple interface situations. In my experience it is next to impossible to max. out a 10G connection with a single NFS connection running over it. The NICs have several independent queues like so (systat -ifstat): ixl0:aq ixl0:rxq0 ixl0:rxq1 ixl0:rxq2 ixl0:rxq3 ixl0:rxq4 ixl0:rxq5 ixl0:rxq6 ixl0:rxq7 A single connection will only use one of these, limiting the overall throughput. Spreading load across multiple connections sounds quite useful to me in this situation. cu Gerrit
