The X Carve comes with default acceleration settings which are quite low as Newton figured out that the force on a mass depends on the acceleration, at high acceleration settings you will put a lot of strain on the belts etc.  
Grbl decelerates before taking a corner before gaining speed again. So on a job with lots of details it will continuously decelerate and accelerate and lose a lot of time doing that.
