<p>How much difference? Listing 7.2 runs in 121 &micro;s&mdash;40 percent faster than Listing 7.1, even though Listing 7.2 still uses <b>LOOP</b> rather than <b>DEC CX/JNZ.</b> (The loop in Listing 7.2 could be unrolled further, too; it&rsquo;s just a question of how much more memory you want to trade for ever-decreasing performance benefits.) That&rsquo;s typical of local optimization; it won&rsquo;t often yield the order-of-magnitude improvements that algorithmic improvements can produce, but it can get you a critical 50 percent or 100 percent improvement when you&rsquo;ve exhausted all other avenues.</p>
