[please help] Scratch speed line test

Instructions

As we all know, scratch is notoriously slow. But how slow? This project tries to find that out - by drawing a buncha pen lines with a sprite. You can set a line amount by using the slider. The number output says how many lines are actually drawn, the other slider should just make it easier, it isn't linear. So you start by moving the slider and trying to find the point where it really slows down. Now you move your mouse cursor slowly and see if you get an instant brightness reaction. If yes, then increase the value. If not, then decrease it. Try to find the highest slider value without any lag and post it in the comments! Also try it on forkphorus: https://forkphorus.github.io/#414616964 So, what is this for, you may ask. Well, if you wanna make a pen game, you have to know how much lines per frame you can draw. And since I don't know how your PCs are, this should find it out.
