If you need to ask, you probably shouldn't.

With OpenBSD, an excellent rule to follow is, ``If it ain't broke,
don't fix it.''

Tweaking for the sake of tweaking is *very* unlikely to save you more
time when using the system than you spent in tweaking it. It's also
*very* likely to cause you to break something that'll take more time to
fix than you spent in the initial tweaking--let alone then you saved as
a result of possible performance gains. The people who set those knobs
in the first place generally know what they're doing, and they want you
to get the most out of the system.

You might be left thinking that OpenBSD is fragile, or wonder why there
are these knobs that can be twisted. Consider a car. You can adjust the
timing, if you like. If it's a race car, being driven at the limits of
its performance, careful adjustment of the timing is critical to
getting the most out of the engine. However, blindly advancing the
timing of the engine will *probably* give you more power--but at the
expense of possibly damaging the engine, and certainly altering fuel
consumption, pollution emissions, and the like. If you understand
everything that's going on, you may decide to advance the timing. Or,
you might come to the conclusion that you're better off retarding the
timing or leaving it alone. But if you don't know *what* you're doing
and *why* you're doing it, you're best off leaving it at the
manufacturer's specs--especially if you're not having any problems
indicative of misadjusted timing.

Cheers,
