I'm not sure why you are talking about performance now.

ECMAScript's language specification led to many competing implementations.

And having an alternative implementation of Perl would naturally involve the need of a specification and/or help define it.

perlito was already mentioned twice in this thread.

Haukex' webperl is feature complete (not "reduced") but it's not written in JS (apart tiny parts for bridging), but cross compiled to WebAssembly
