I have heard that replacing for loops with repeated commands is sometimes more efficient, but I don't think that was the reason here, especially for 18000 iterations.

"18000 duplicated lines that were manually copy pasted by a monkey"

Here, I fixed your typo.

@iiii yup, and its been pretty useless for the last 20+ years, atleast in compiled languages as any sane compiler does it for you when it is beneficial. (i.e whenever unwinding won't cause you to flood the l1 cache)

Now now, I think that person is a great candidate for Yandere Simulator development.

@theabbie That depends on the language, and if the loop only goes once or twice or how many times the compiler/interpreter need to see before unwinding the loop.

@theabbie this kind of optimizations isn’t done by the compiler?

It's 2021... the guy obviously identifies as a compiler.

@theabbie I wouldn't do it by hand in most cases though, the compiler can often figure out when it's a good idea to do it
