Compared to Bush, how much has Obama done?

Compared to Bush in his first 6 or so months, has Obama done less or more? I'm not necessarily looking to hear your opinion on whether it has been good or bad, I just want the facts. Saying Obama has done nothing does not help because it's neither true/helpful. I have a feeling I'm just going to get partisan ideologues feeding me the typical BS, but I just want a pragmatic list or general comparison of what both had done as president up to the 6 month mark. I'm relatively young and have only been interested in politics for a short while so I want to understand how much presidents can actually do in a 6 month time-span.
