Answer 1

On the screen it is written in English and white: the script ate all the memory. That's the whole "limit".

Answer 2

try to use web workers , but it seems to work a little slower (but you can officially use multithreading by running several of them)
to advise how to speed up, you need to understand what kind of task and algorithm you have
