Quote:What is the fastest way to loop thorugh a long array
First of all, a list of 121 is not long, long usually start after 100,000.
Whatever the flavor of the loop (for, while ...), by itself, it is fast.
What make a loop slow is what you do inside the loop.
The problem is that you told nothing of interest, we have no idea of what is the game or how you did the loop.
Before thinking to multithreading, you need to think about optimization.
