That may be right, but "better" order filling or any other bells and whistles will not help to beat the market or gain substantial benefits from it in the long run. I've seen traders sending orders in slow command line and making substantial returns, so the tool perhaps is not the instrument for success on the market in the long run. It's like saying that green car will drive you faster/safer/etc compared to black or white cars, while the most important contribution to speed and safety lies between steering wheel and driver's seat.

Needless to say orders may not (and most certainly will not) be filled when market (or HF) make sharp moves.
