I’ve always used “0″ too, this will help for boids-style (sims)work big time, thank you!

i tested this with 5000 objects that they are simple spheres. i made 2 components that they have one coroutine with two lines of code.
the FPS with return 0 is 200 but with return null is 230.
this is the coroutine

IEnumerator test2()
{
while (true)
{
transform.Translate(Random.Range (-30,30),0,0);
yield return null;
}
}

thank you

Yield will still generate overhead. This trick just removes some of it

Very helpful trick! I also noticed that yield generates a huge pause when switching (according to the profiler in 2.6) up to 15-20 ms and it results in the frame drop….
