Some older NFS servers might incorrectly handle NFS version 2 READDIR requests for more than 1024 bytes of directory information. This is due to a bug in the server implementation. However, this parameter contains a workaround in the NFS version 2 client.
When this parameter is enabled, the client does not generate a READDIR request for larger than 1024 bytes of directory information. If this parameter is disabled, then the over-the-wire size is set to the minimum of either the size passed in by using the getdents(2) system call or by using NFS_MAXDATA, which is 8192 bytes.

Examine the value of this parameter if an older NFS version 2 only server is used and interoperability problems are seen when trying to read directories. Enabling this parameter might cause a slight performance drop for applications that read directories.
