No Load speed for a servo is the same as "free speed" for a motor - the speed that it moves when there is no load (other than the internal friction and inertia of the motor and gearing). Another way of viewing this is as zero output torque (all of the torque of the motor has been used up in friction). As was noted earlier, if you assume that the torque and speed scale in an inverse linear fashion (usually a decent approximation), the peak mechanical power output is at one-half of the no load speed, and one-half of the stall torque, which is one-quarter of the max power rating.
