However, to the best of my knowledge, none of the extant clients are using it effectively. (Solaris10 shipped with minimal delegation support.) I am just testing Delegation stuff, so I should know soon how much it helps performance. But a production quality implementation of NFSv4 with delegations (client side) isn't out there at this point, from what I know. rick
