Frankly, it sounds like your manager doesn't *really* know what he's talking
about. There is far, far more money wasted on fixing and customizing and
maintaining hard-to-read code than there is lost on inefficient code. Now
it just could be that your compiler does a crappy job with these things and
it is slow. But on the other hand, it still might not matter! (Does it
really matter to the user if something takes .03 seconds or .01 seconds?)

Who said his boss had to prove anything?

Doesn't that flow from the questions I answered? What are those if not
requests for proof?
