Alright, we all know that Scratch 2 is much faster than Scratch 1.4, but I am wondering if that is due to the new interpreter code. Basically, in Whiskers (which aims to add scratch 2 to 1.4), I've noticed that script execution is MUCH slower than 2.0, which leads me to believe, is it the new interpreter in scratch 2 that makes it faster? I want to know that way I know if it is worth it to rewrite the interpreter in Whiskers.

tl;dr: Is the new interpreter what makes scratch 2 run faster?

I think Squeak is just kind of slow…

Better to invest your time optimizing Squeak itself, I think.

Yeah, I know , but would porting the interpreter from 2.0 to 1.4 to more harm than good, or would it be worth it in terms of speed (without optimizing squeak too much)?

You'd have to try. See online how much optimizing Squeak has helped, though. If a quick optimization is going to make it run 6 times faster, do that instead of re-implementing the 2.0 interpreter

Alright, I'll get back to you guys on what happens…

Alright… I couldn't optimize Squeak too much, but I completely rewrote the interpreter from scratch (no pun intended), and I made it about 3-5x faster than NuScratch's interpreter (or about 10x faster than original scratch!). With a few more tweaks, I can expect to get some much needed speed back into the version of scratch made from squeak!

Wow! That is great! Keep up the good work @NoMod-Programming
