We've gone well past the bounds of normal GameMaker use and into the realm of the truly bizarre. You can try this yourself at home if you want to, but if it blows up in weird ways, you're on your own.

The profiler:

All GameMaker optimization videos:

The tier list:
forum.gamemaker.io/index.php?threads/the-ultimate-gamemaker-optimization-tier-list.122141

This trick is untiered because as far as I know I'm the only person who uses it and I was running out of characters in the posts, but if I were to add it it would get its own tier between B and C.

0:00 Introduction
1:30 a GameMaker history lesson
5:31 script_execute_ext
8:22 please stop being weird about where you put your i++, I will show the bytecode to prove it makes no difference
8:52 How long does it take to find the smallest number in an array?
12:10 Using script_execute_ext on draw functions
20:16 When this doesn't make any sense
23:49 When this is just slower than leaving it alone in the first place
28:14 The end
