Servo speed

Kind of.
Say if the servo is at 45 degrees and you want to move it to 90 degrees.
If you just change the pulse width to whatever's right for 90 degrees it moves at full speed.
If instead you send it 45.5 degrees, then 46 degrees, etc, etc, then you have speed control. Just like moving the sticks on the transmitter slowly.

Just to add to MarkD77's post, no torque would be lost if you move in the small steps like he suggested. Note that this effect will only SLOW the speed that you move from position A to position B. From your post, I assume that is what you wanted since ther is no mention of gears.

If you want to move faster, then gears will be needed and torque will be lost.

The posts above are correct provided the discretization of the command signal is not a problem and the servo's controller can respond properly (doesn't overdrive the output signal to overcome frictional losses, etc.) to the smaller steps.

Above, I was referring to a desire to speed up a servo. Since you referred to a change in torque, I assumed a mechanical gearing was implied.
