What I want is a simple new readable sysctl, something like:
hw.clockrate: 132
I think that this would be useful both for development (how fast
is that stupid machine down in the bunker?), and system admininstration
(who needs a cpu upgrade this year?).
Doing this for Pentium and better systems should be trivial. Doing
it for 486 and lower would just add a timing loop. Doing it for SMP
would be harder.
hw.cpu0.clockrate: 233
hw.cpu1.clockrate: 233
Possibly? The implementer gets to pick a better name than these.
