[cryptography] Javascript scrypt performance comparison

Hi all,

does anyone ever made a performance comparison of existing JS scrypt
implementation?

Currently there are those three:
- scrypt-async-js https://github.com/dchest/scrypt-async-js/
- js-scrypt (emscripten compiled) https://github.com/tonyg/js-scrypt
- webgl-scrypt https://github.com/Kukunin/webgl-scrypt

Anyone ever analyzed/compared them?

Also for upcoming implementation extending scrypt concept, like
yescrypt/yescrypt-lite it would be very interesting to think how to make
it faster in the context of the browser/javascript/html5.

Being able to exploit fully WebCrypto/WebGL to deliver quasi-native
performance in the browser would be cool.
