I don't claim that Listing 21.5 is the fastest possible way to do a
TCP/IP checksum on a Pentium; in fact, it isn't. Unrolling the loop one
more time, together with a trick of Terje's that uses **LEA** to advance

more time, together with a trick of Terje's that uses `LEA` to advance
ESI (neither `LEA` nor `DEC` affects the carry flag, allowing Terje
to add the carry from the previous loop iteration into the next
iteration's checksum via **ADC**), produces a version that's a full 33
iteration's checksum via `ADC`), produces a version that's a full 33
percent faster. Nonetheless, Listings 21.1 through 21.5 illustrate many
of the techniques and considerations in Pentium optimization.
Hand-optimization for the Pentium isn't simple, and requires careful
