In my opinion discussions on performance theory are so subtle and can be so misleading that you really need to model and demonstrate e.g. reduced instruction count, memory reads, or other metrics in order to prove out your claims. Otherwise it’s nearly useless. The Go blog post about performance tuning versus C++ is a great model to follow. The claim in this article is not 2x, it’s “50% of CPU was consumed by this loop, now it’s ~0%” I’d love to see a series of improvements and how they impact the machine behavior / speedup....
