Anyone reading that advice: ignore it. You cannot use bogomips to meaningfully
compare processors.

There is a "perf" package complementing the linux kernel package, for example if
the kernel package is linux-image-4.17.0-3-amd64 the perf package is
linux-perf-4.17. Also, take a look at this web page
http://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html about profiling by
Brendan Gregg.
