This is a speed test: The top one has the script "Forevever: move 1 step, move one step, move one step, move one step" The second to the top one has two forever loops saying "move 1 step". The third one from the top forever broadcasts a message to itself saying to move one step. The fourth one has a "forever: move 1 step" script. And finally, the fifth one from the top forever broadcasts a message telling it to move 1 step and waits. You can use these results when making a project so you can find the speediest scripts.
