NFSv4.1+ differs from earlier versions in that it always performs trunking discovery that results in mounts to the same server sharing a TCP connection. It turns out this results in performance regressions for some users; apparently the workload on one mount interferes with performance of another mount, and they were previously able to work around the problem by using different server IP addresses for the different mounts. Am I overlooking some hack that would reenable the previous behavior? Or would people be averse to an "-o noshareconn" option? --b.
