There is not any intentional delay there, and there is no option to lift before the move finishes. 

If you are using the standard (Inkscape-based) software and using standard (or close to standard) settings, then what you are likely seeing is a combination of two effects. These are the slowing down of movement as it approaches the end of a path, and the physical time needed to lift the pen.
You might try, under the Options tab, selecting the option to move at a constant speed when the pen is down. This will make it so that the movement does not slow down as it approaches the end of a line. Slowing down takes time, and can lead to pooling of ink there.  You can’t go quite as fast with this mode, but it may help with the issue that you’re having.
The second effect is the physical time needed to lift the pen. You can make the servo raise faster by adjusting the Pen Raising Speed in the Timing tab. You can enter a value as high as 500 there, to make the servo move as fast as possible. However, even more important than this is that you pick an appropriate set of pen-up and pen-down positions in the Setup tab. Ideally, when you are in the pen-down position, there should be only a very small gap (1-2 mm) between the servo “horn” that performs the lifting and the metal surface that it lifts. If you have a larger gap than this, you will notice a delay as the servo motor has much further to travel before it actually starts lifting the pen.
