Lets say you get mouse events 100 times a second and and you have 
10 function calls to filter through the gui tree, and your 
overhead for passing on the stack is 20 cycles.

(100*10*20) = 20,000

And your CPU is 2Ghz, so...

2,000,000,000 / 20,000 = 100,000

So what you're optimizing for is like 0.001% of your cpu time.

It's utterly irrelevant.
