We care about these facts. Usually we test under linux & windows,
and the results are usually confirmed  also for macos.
We have not noticed slowdown.

no, it's ok, we can keep track that there could be  a problem with
x86_64-darwinlegacy.  The next step is how to compile a
x86_64-darwinlegacy binary with the same optimization flags that I use
for luatex under x86_64-linux
(as already said, these flags can change in texlive, as happened for i386-linux)

hm no, the point of Hans is more general, not directly tied to this
case: better to  optimize
lua code, because is very  easy to quickly write  slow lua code.
This case is different, and it's not important if  it's good or bad code.
