I'm sorry, I don't remember the exact figures.  I think it was in the
order of 15% - 20% but it wasn't scientific as we weren't serious about
deploying it at the time (an upgrade would require newfs, and we didn't
have swing servers at the time).

Of course, with faster hardware (new Linux servers) I think that we would
have been better off overall with a NAMEI implementation.
