I know you are a fan of testing things thoroughly in the test suite, but I
have to say that it is getting out of hand, in particular due to our
over-use of shell script idioms (which really only run fast on Linux, not
a good idea for a portable software).

How much effort would it take to optimize a /bin/sh?

Would replacing uses of fork+execve posix_spawn be fast and
portable enough?

Even on Linux, performance sucks for me.  I've been hoping dash
can use posix_spawn (or using vfork directly) to see if that can
help things.

Busybox hush uses vfork.on no-mmu builds. You could try it out. I
don't know how complete it is though.
