It'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
**FindIDAverage** that was produced by looking at the assembly output of
`FindIDAverage` that was produced by looking at the assembly output of
MS C/C++ and tightening it. Listing 8.3 eliminates all stack frame
access in the inner loop, but that's about all the tightening there is
to do. The result, as shown in Table 8.1, is that Listing 8.3 runs a

Listing 8.4 tosses some sophisticated optimization techniques into the
mix. The loop is unrolled eight times, eliminating a good deal of
branching, and **SCASW** is used instead of **CMP [DI],AX.** (Note,
however, that **SCASW** is in fact slower than **CMP [DI],AX** on the
branching, and `SCASW` is used instead of `CMP [DI],AX`. (Note,
however, that `SCASW` is in fact slower than `CMP [DI],AX` on the
386 and 486, and is sometimes faster on the 286 and 8088 only because
it's shorter and therefore may prefetch faster.) This advanced tweaking
produces a 39 percent improvement over the original C code—substantial,
