Well, during the Prolgue the EH was already warped into the Peragus field. It only HAD to fly a short while, and as you can see in the cutscene that was done in a very slow flying rate and without any balance in the ship...
And now see Malachor V; Top speed, perfectly balanced and flies along part just when the movie ends, how much longer does it have to fly after that to reach a planet?
