I was about to propose something like this. I don't recall what's in the guide, but I use pstat -T to check the number of available vnodes. There are many different ways this could be set better by default. I'm still formulating how I think this should be done, but IMHO maxusers is a bit archaic. Is it so sacrosanct that we couldn't implement something else to make tuning NetBSD more intuitive for the "average" user? It's always seemed odd to me to base tuning of vital system parameters upon some constant named something so abstruse that our documentation must clarify it in order for anyone to ever hazard a guess as to what it really does! How about raising the default at least on platforms where memory is usually plentiful, e.g. amd64? If someone's using the amd64 port in, for example, an embedded application with little memory, presumably this user would already be proactively tuning the system. On the other hand, there are surely more elegant [and complex] ways to go about this. We could have it scale by default along with other vm parameters, etc. Any proposals? Regards, --Blair
