Anyone reading that advice: ignore it. You cannot use bogomips to meaningfully compare processors.
The reason being?
The kernel uses it just fine for the clock calibration.
As far as I remember, the bogomips number has consistently been twice
the current clock frequency on any x86 PCU I have ever run Linux on.
How can you measure and compare processor performance from the mere
clock frequency ?
