This tests the speeds of the thing you are currently using to view it. E.G: turbo mode will produce a much higher speed score than the normal mode. You could use it in a game to test that a game is running on a computer good enough to play it. Please give me credit. PLEASE NOTE: IF ANY OTHER SCRIPTS ARE RUNNING IT AFFECTS THE SCORE. It works by counting how many times the script can change a variable in 2 seconds. I find that the scratch program and the java player acieve 1-2. But the flash player achieves 8000 on my computer. No wonder I like the flash player better.
