I didn't intend it as a negative tone. It is meant as an observation: while the raw system speed has increased orders of magnitudes, certain high-level operations seem to remain constant speed over time.

The time it takes to booting an operating system, start a program, compile a program or run a test suite seems to remain somewhat constant over my career.

It indicates that the determining factor is not the clock speed of the underlying system but instead the pain tolerance of the users or developers.

Thank you for answering and explaining @VMG! Yes exactly, some features of software will naturally gravitate to some values where they are good enough and something else becomes the bottleneck and determining factors. I still believe though there will be a niche space for people that need the extra performance because their use case takes an advantage from it.
