prlctl talks a complicated protocol (involving SSL and XML wrapped in
custom binary structures) to prl_disp_service.  vzctl talks to the
kernel directly.  Thus, prlctl is expected to be slower.  The question
may be how much slower is expected.  I don't know if your findings are
within expectations of the developers or not, but these findings don't
surprise me (as someone who played with prl_disp_service protocol).
