nfs4 mount options rsize wsize

["Andreas B. Mundt" <andi.mundt@web.de>]

Hi,

I am wondering what the 'best' options mounting the home directories
via NFSv4 are.

IIRC, by default debian-edu uses rsize=32768,wsize=32768, which has
been adopted by debian-lan too.

Running a test without defining rsize,wsize on 3 different setups, I
got the following (remove rsize,wsize in LDAP and check with 'mount'
after mounting the directory):

    virtual machine setup:   rsize=wsize=131072
    real hardware 1      :   rsize=wsize=262144
    real hardware 2      :   rsize=wsize=524288

All values are considerably larger than the values defined manually.
It would be nice to understand the reasons why such a small value has
been chosen in debian-edu.

Best regards

     Andi
