Actually, having these computed dynamically is much better than
having to manually tune them every time your mix of programs
change or you add memory except in some very unusual circumstances
like a server that does a single job forever. In the general
case consider whether you'd rather hire an expert admin to
keep your system tuned or buy an extra gig of ram and let the
OS figure out how to use it.
