The Sailrite has a max speed of 600 stitches per inch, and a regular industrial sewing machine will do 3000 stitches per inch. Not that the speed makes a difference, no one can sew at the max speed for very long. Your machine is geared down so that you are getting 1.5 ft. lbs of torque out of it, which is the same as a 1/2 hp motor with no gear reduction.
