Edit: I thought C optimisation wasn't working but I repeated the tests and now C keeps having the same speed with optimisation despite passing the number as command line argument. This also suggests that the value is not calculated at compile time..

thanks for this insight, I've countered the problem with command line args. Now the C compiler can't guess how many loops will be made and therefore the test shows the same speed as C without using optimisation. But Go keeps having consistent speed, faster than C. I'm curious what kind of optimisation the Go compiler applies. See the update for further details..

the problem is that Facebook didn't ask explicitly if the user wants to activate that feature. Not everybody is sufficiently tech savvy to know what that icon means

I think the idea of the creators was to make people independent from a telephone company, no need to even own a SIM card..
