My point is that construction time as a percentage of overall time
probably only matters for small documents.  If you're parsing a 2 Meg
file, you probably don't notice it takes 20ms to get the parser
constructed.  But if you're parsing 500 byte files, you do notice.

Yep, right now we're just armchair performance tuning.  :-)
