Pulse frequency and Servos

If there is a delay already implemented in the servo functions, how can I change this value (e.g. if the servo allows a very high pulse frequency)?

I don't have the answer for this question
EDIT The post with the link to "analogWrite" reference page was deleted because it does not apply to servo library.

Does anyone know what the OP is asking ? Is his question about duty cycle of the servo pwm ? (he doesn't mention that. His question is about delays and I don't know what delays he is talking about. When I look at the servo pwm waveform on the scope the only thing that might be construed as a delay (by a newbee) is the off time of the pwm waveform.
