I used the DIY perf PIT, and my observations are that there is a lot of 
noise in their test runs due to small sample sizes.

Right.  I wanted to run sanity tests to verify that I had not made things 
worse.  Performance improvement was not a primary goal, so I did not 
spend many resources evaluating potential positive performance impact.
