How much of a load does auditing have? White Paper?

Is there a white paper out there that discusses what the load is for turning on auditing?  

In the past when we had short occurrences to just "try it", it seemed to put almost a 20% load which is unacceptable. Then again, you don't have to audit EVERYTHING.  

Is there a good paper and/or book on the fine details on the subject?  

What, if anything, have you done to sort of satisfy Sorbanes, etc?  

The questions are beginning to be asked here. There is probably this "glow" that auditing will allow them to filter through massive amounts of data to find the culprit.  

Thanks.
