<p>It&rsquo;s hard to squeeze much more performance from this code by tweaking it, as exemplified by Listing 8.3, a fine-tuned assembly version of <b>FindIDAverage</b> that was produced by looking at the assembly output of MS C/C<small>++</small> and tightening it. Listing 8.3 eliminates all stack frame access in the inner loop, but that&rsquo;s about all the tightening there is to do. The result, as shown in Table 8.1, is that Listing 8.3 runs a modest 11 percent faster than Listing 8.1 on a 386. The results could vary considerably, depending on the nature of the data set searched through (average block size and frequency of matches). But, then, understanding the typical and worst case conditions is part of optimization, isn&rsquo;t it?</p>
