The "numbers from" block is ridiculously quick, how does it do it?
I made a comparison project here and it clearly shows the speed.
"munbers" is the custom block that I made to recreate it.
And similar question I guess, why is the primitive ide_blocks so slow?
I think that's mostly just drawing the list. Try setting it to a hidden variable, so it doesn't have to draw anything.
That was a good idea, doesn't seem to be the cause though.

That's because the actual numbers from () to ()
block uses the zip function that is used to make things fast. Zip might use a compiler to make things fast.
