David, Do you have timed_statistics set to true? If not, you need to do so. Although I am pretty certain that this is the case, but let's assume that you truly waited 0 seconds. If you were able to remove ALL of the latch free events, you would improve the response time in the system by 0 seconds. Not exactly a cost-beneficial activity.
Set timed_statistics to true and then look at the wait analysis. Focus on seconds waiting, not total waits. There is where you will find the benefit.
