That clarifies it. So for I don't specify any values for NMBCLUSTERS and NBUF, leaving maxusers at 512, and just watch how the machine performs. I just thought about increasing NMBCLUSTERS because somewhere (I don't remember) it was mentioned, that some new code (larger default buffers somewhere in the ip stack?) could make one run out of them. But I guess with maxusers=512 I'm already on the safe side.
