That's only true when you know the length before serializing the 
payload. For dynamic content like JSON or a Wave stanza, which are 
frequently short, the medium length of the serialization buffer is 
better, which is why the 1/2/8 variations like option #2 are good 
compromises.

1 is best for hand-optimized protocols like Quake.
2 is best for dynamic content that is frequently short
8 is best for sendfile
