It's called *bogo*mips for a reason (see 'bogus' in an English
dictionary). It's a calibration value and doesn't have any meaning
beyond that. It's only comparable betwee

It depends on the CPU, but on a 7447A, yes.

Doesn't the Mac Mini also have this CPU? If so, does this mean
that the CPU in the Mini is running slow?

Hi !
It seems the new laptops are booting with CPU set to low
speed. /proc/cpuinfo outputs the wrong fequency (thinks it's high speed)
but bogomips shows that it's running at about half speed. This patch
against 2.6.11 (will not apply on 2.6.10) adds proper cpufreq support so
that the boot speed i
23 matches
