The miniaturization of semiconductor transistors has driven the growth in computer performance for more than 50 years. In this paper, we advocate that in many interesting cases, a careful static analysis of assembly code can achieve similar results at a much lower cost and with a better accuracy. Since ASTEX, contrary to previous work, doesn't assume shared memory, the speculation is performed on control flow and data layout also. Therefore, a programmer extracts pieces of code from large programs, as candidates for the performance tuning. Three performance quality metrics are defined and evaluated for two simple codelets, demonstrating several modes of performance failure and the weakness of intuition in detecting them, as well as illustrating how better tools could help lead to better computer systems.
