If I don't care about authentication through kerberos, does NFS-v4 give me any advantages over 3? According to wikipedia "Version 4 (<a class="external" title="http://tools.ietf.org/html/rfc3010" href="http://tools.ietf.org/html/rfc3010">
RFC 3010</a>, December 2000; revised in <a class="external" title="http://tools.ietf.org/html/rfc3530" href="http://tools.ietf.org/html/rfc3530">RFC 3530</a>, April 2003), influenced by <a title="Andrew File System" href="http://en.wikipedia.org/wiki/Andrew_File_System">
AFS</a> and <a title="CIFS" href="http://en.wikipedia.org/wiki/CIFS">CIFS</a>, includes performance improvements," but does the tuning from the NFS part of the performance howto make that redundant?
