That is a better than average benchmark page.

As alluded to in https://news.ycombinator.com/item?id=43319010, I see these tests were collected against just 2 Intel and 2 ARM CPUs. So, if you are looking for feedback to improve, you should probably also include (at least) a AMD Zen4 or Zen5 in there. CPU & compiler people have been both trying to "help perf while not trusting the other camp" for as long as I can remember and I doubt that problem will ever go away.

A couple more CPUs will help but not solve generalizability of results. E.g., if somebody tests against some ancient 2008 Nehalem hardware, they might get very different answers. Similarly, answers today might not reflect 2035 very well.

The reality of our world of complex hardware deployment (getting worse with GPUs) is that "portable performance" is almost a contradiction in terms. We all just do the best we can at some semblance of the combination. The result is some kind of weighted average of "not #ifdef'd too heavily source" and "a bit" faster "informally averaged over our user population & their informally averaged workloads" and this applies at many levels of the whole computing stack.

EDIT: And, of course, a compiled impl like Cython or Nim is another way to go if you care about performance, but I do understand the pull & network effects of the Python ecosystem. So, that may not always be practical.
