Just a thought, but has anybody considered adding a (possibly
platform-specific) tuning(7) manpage, like FreeBSD has?

That would be an ideal place for documenting performance tweaks
that we may want to suggest but not enforce by default, also
kernel options to particular roles, etc.

For all I know we already have this resource
 - the mailing list archives spring to mind :) - but this would
be something that would be easily accessible, and could be maintained
along with the system (sometimes it's hard to tell whether a particular
tweak still applies to a moderm NetBSD box).

And yes, since I'm the evil genius behind this, I'm prepared to
contribute if people think it would be handy (still pretty new to
NetBSD, so would happily accept contributions from gurus).
