Linux has had an "nconnect" NFS mount option for some time. It specifies that N (up to 16) TCP connections are to created for a mount, instead of just one TCP connection. A discussion on freebsd-net@ indicated that this could improve client<-->server network bandwidth, if either the client or server have one of the following: - multiple network ports aggregated to-gether with lagg/lacp. - a fast NIC that is using multiple queues It does result in using more IP port#s and might increase server peak load for a client. One difference from the Linux implementation is that this implementation uses the first TCP connection for all RPCs composed of small messages and uses the additional TCP connections for RPCs that normally have large messages (Read/Readdir/Write). The Linux implementation spreads all RPCs across all TCP connections in a round robin fashion, whereas this implementation spreads Read/Readdir/Write across the additional TCP connections in a round robin fashion.
