cache: where to turn-on?

http://www.youtube.com/watch?feature=endscreen&NR=1&v=o6PoZi-HEPw is a video I have just watched about how to speed-up a site. Step one is to turn on the internal cache in Drupal. Can anyone find this in the Commerce menus or any other way?

For authenticated users, you can just use some cache modules or you can do a big update in your server to handle requests faster.

But, for now, enable cache in Performance page of Settings section.
