Is it true that setting the wsize and rsize options when mounting a
filesystem only affects the data transfer size over the network and
that the amount of data sent is related to the file system block
size? I am talking about NFS under SunOS 3.5 here but general comments
would be welcome also.

I'm using a very slow network connection (9600 baud SLIP to be exact)
and analysing read times it seems that 8KB transfers are being
performed no matter what rsize and wsize settings are used. 

Is this an unavoidable feature of the Berkeley file system or buffer
cache?
