Be careful with roundrobin or loadbalance. Both of them will distribute outbound traffic across all ports, but at the expense of causing your NFS clients to receive out-of-order TCP packets. This increases their CPU load. You may find that performance with roundrobin is actually worse than with LACP because of the out-of-order issue. Also, neither roundrobin nor loadbalance will help distribute inbound traffic. -Alan _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
