For or foreach loops in Unity3d?

Question

Unity

Hello, can you advise which is better private use of for or foreach loop, which has the least impact on performance in a Unity3d project?

Answer 1

We use foreach at home, they are more convenient, but we don’t observe any brakes. If the profiler says that it slows down, replace it with for. Do not bother with optimization ahead of time, write as convenient. Brakes will appear, look at the profiler, draw conclusions.

Answer 2

in fact, for will be faster. mono will recompile foreach and while into IEnumerable + switching methods

Answer 3

mono seems to compile them in while yes. but not the fact that still. for example, if you use a compiler from the studio, then there is no such problem and foreach fly for generics of the List<> type. you need to research ..
here is sort of relevant research:
