Description
linuxtips.md mentions CPU governors and suggests performance. However, after the introduction of pstate in Sandy Bridge, the default processor frequency scaling became very responsive. In my own benchmarks, I frequently get much (10–30%) better performance from just working with the default than performance. Just not bothering to set CPU scaling may be the most realistic scenario for most recent computers (Sandy Bridge appeared after 2011).

Research direction
Start with the CPU frequency scaling and boosting section in doc/linuxtips.md, then review the linked Arch Linux guidance and the issue's benchmark observations. Update the governor advice so it reflects current processors and realistic defaults; done means the documentation no longer presents performance as universally preferable.
