File reading is probably faster because of the read ahead, but when 
you write back blocks to a remote NFS, the server probably waits for
acknowlegement of a successful write, i.e. the server waits until
it receives the ack, before it trashes the cached block.

I would like to know if there is detailed answer to this.
