Here's an easy thing to try and it doesn't require you to be pushy. Keep careful track of the work you do. Don't oversell anything, just state the case. Email the list weekly to your supervisor. Call it weekly status. If you don't see a change in your situation, either you're not as big a producer as you thought or your supervisor doesn't care that you work harder than your peers. In any case, this is easy to do, doesn't call for grandstanding and will at least let you know where you stand.
