> 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).
