/dev/zero is a special file in Unix-like operating systems that provides as many null characters (ASCII NUL, 0x00) as are read from it. One of the typical uses is to provide a character stream for initializing data storage.

NFS tuning can occur on both server and clients. You can also tune both the NFS client and server TCP stacks. In this article, I've broken the list of tuning options into three groups: (1) NFS performance tuning options, (2) system tuning options, and (3) NFS management/policy options. The options for these three categories are listed below. 1.

Optimizing NFS Performance Careful analysis of your environment, both from the client and from the server point of view, is the first step necessary for optimal NFS performance. The Later (Section 5.3 and beyond), server side issues will be discussed. cases, these issues will not be limited exclusively to one side or the other,

From Wikipedia: . Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed.
