There is a note in the performance section from the NFS-HOWTO[1]. It suggests adjusting the r- and wsize mount parameters:
_._. .._ _ .... . ._. . __..__ _._. .._ _ .... . ._. .
Directly after mounting with a larger size, cd into the mounted file system and do things like ls, explore the filesystem a bit to make sure everything is as it should. If the rsize/wsize is too large the symptoms are very odd and not 100% obvious. A typical symptom is incomplete file lists when doing ls, and no error messages, or reading files failing mysteriously with no error messages. After establishing that the given rsize/ wsize works you can do the speed tests again. Different server platforms are likely to have different optimal sizes. _._. .._ _ .... . ._. . __..__ _._. .._ _ .... . ._. .
