> Currently, NFS creates an input steam for each read request and closes it after the request
is served. With lots of read request, the overhead is significant. 
> Like for write request, NFS should create input stream for a file and try to share it
with multiple read requests. The stream can be closed if there is no read request for a certain
amount of time (e.g., 10 sec).
