Yeah, section seemed like some weird brag.
The details he documented don’t seem relevant for what he did and nothing performed would seem to stress even a low end ancient system.
Definitely felt like a brag to me.
Only thing that makes me think otherwise is he also documented the line counts of the scripts. Seems more like a bizarre obsession with minutiae… (would have been more meaningful to document the git commit/branch for a GitHub project instead of the line count!!)
