Use the step_threshold configuration option.  From the man page:

       step_threshold
              The maximum offset the servo will correct by changing the  clock
              frequency  instead  of  stepping the clock. When set to 0.0, the
              servo will never step the clock except on start. It's  specified
              in  seconds.  The default is 0.0.  This option used to be called
              pi_offset_const.
