Quite right, but if you ship software to customers you'd have to profile on a variety of CPUs or risk regressing on other models. Profiling on recent Intel x86_64 CPUs gave me the (perhaps false) impression TFA author writes for a known or even controlled environment. That is indeed not a luxury everyone enjoys, so I raised a portability concern. However, the potential benefits of cheap horizontal scaling also extends to said customers.
