It is important for people to understand that LADDIS is a very hard load, and in real-world environments people will often see much higher throughput than LADDIS would seem to predict. I recently got a note from a customer "complaining" that his F230 was running at a sustained load of over 3300 ops per second, which is over double the LADDIS "limit" for that system.
But don't assume that LADDIS results will limit the performance that you see in a particular real-world environment.
I see your point about NFS ops. I would guess then that if this customer was seeing a high percentage usage of the cpu then that would be the indicator that the box was overloaded. And that's not something one can easily extrapolate from the cpu performance of Suns or any other boxes. Estimating the size of filer needed doesn't seem very straightforward then, except by disk sizes.
