title: How can I test the user's computer's processing power using Javascript?
body: <p>I made a pretty CPU intensive webpage with lots of CSS3 and Javascript. I want to use Javascript to test if the user's computer is capable of handling the scripts. I think a possible method is to run some CPU intensive scripts and see how long it took. However, I don't know how to actually implement this.</p>
