Calling public methods with in the component without 'this' is faster

I did some testing whether i should use this to call public methods with in the component and it seams that calling a public method with in the component is faster if you do not use the 'this' .

I created 2 simple cfc that were calling internally a public function the one with this.function name and the other one the function name directly not using the this was faster for 15-20 %
