Slow reaction time using Arudino Pro Mini with NRF24L01 Transceivers

Well, I am using a 5v pro mini to get as much voltage as I can output and it goes to 2 potentiometers and a switch to control a system that is communicating with the NRF24L01 transceiver module. The receiving system is an Arduino UNO connected to a DC motor and 2 servo motors. I just am not sure why there is the little delay though I feel like I am missing something..
