In the spirit of experimentation, I've put together a set of patches that implement setting up multiple TCP connections to the server. The connections all go to the same server IP address, so do not provide support for multiple IP addresses (which I believe is something Andy Adamson is working on). The feature is only enabled for NFSv4.1 and NFSv4.2 for now; I don't feel comfortable subjecting NFSv3/v4 replay caches to this treatment yet. It relies on the mount option "nconnect" to specify the number of connections to st up. So you can do something like 'mount -t nfs -overs=4.1,nconnect=8 foo:/bar /mnt' to set up 8 TCP connections to server 'foo'. Anyhow, feel free to test and give me feedback as to whether or not this helps performance on your system.
