Hi natostanco,
CloudFlare is great; but Rocket Loader... not so much.
Rocket Loader only 'works' in select browsers; is not recognized by Google Bot; will (almost always) degrade page-to-page navigation/transition load times (since the browser is unable to cache RocketScript .JS); is still in BETA (will work one day, not the next); and is, at least for dynamic WordPress sites, a 'hammer' instead of 'scalpel' -- it's pretty much all-or-nothing, on or off, unless you know PHP backwards and forwards.
Ideally, you'll want to make use of Frank's plugin to defer/asynchronously load your JavaScript. Then, of course, deferred CSS will load properly. (Not to mention all of the other benefits of utilizing 'universally' recognized HTML 5 script attributes).
Best,
AJ
