NFS: rsize and wsize settings ignored on v4 mounts
NFSv4 mounts ignore the rsize and wsize mount options, and always use the default transfer size for both. This seems to be because all NFSv4 mounts are now cloned, and the cloning logic doesn't copy the rsize and wsize settings from the parent nfs_server. I tested Fedora's 2.6.32.11-99 and it seems to have this problem as well, so I'm guessing that .33, .32, and perhaps older kernels have this issue as well.
