buffer cache size

[Jeremy Nussbaum]

We would like to enlarge the buffer cache on a few heavily used nfs
servers.  

1. How do we do it? ( I don't see  any configuration parameters for it,
   unlike system V.)

2. If we can, what is a good starting place for a system with 2gb of disk
   and 32 mb of memory, whose main purpose in life is to have people read and
   write to the servers nfs mounted disk on their own machines?
