    Description

      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).
