This is misleading. First, as other comments have noted, it is comparing multi-threaded/parallelized vs single-threaded, and its total CPU time is much longer than wc's. Second, it suggests there is something special going on, when there is not. Just breaking the file into parts and running wc -l on it-- or even, running a CSV parser that is much more versatile than DuckDB's-- I'm pretty confident will perform significantly faster than this showing. Bets anyone?
