Perhaps NTPD is more concerned with accuracy than with speed of 
convergence.  Others have complained that ntpd converges slowly 
following a cold start.  I think that, clearly, it is best to run ntpd 
24x7 if you want the correct time at all times.

Some very modest hardware in terms of both hardware cost and power 
consumption can run NTPD very well indeed.  See; e.g. the single board 
computers that Poul-Henning Kamp (PHK) uses.
