The voltage applied to the DC motor inside a servo is proportional to the difference between requested position and actual position. So if you tell it to overshoot, it will go faster. This may not be what you want though.

There are also issues with current draw... I believe servos 0 and 1 are on the same circuit, as are servos 2 and 3. So if you have servos 0 and 1 under heavy loads at the same time, that may not work well; it's better to use one servo in 0 or 1, and another servo in 2 or 3.

You can also try using mechanical tricks like gears to increase speed at the cost of torque.
