Indeed, pd-l2ork moves entire selection by tag, so instead of redrawing everything, out issues single tcl/tk command. The only thing that still redrawed every time when displaced is gop-enabled patcher.

I believe Ivica made such a modification in Pd-l2ork-- whatever the case, moving many iemguis in
Pd-l2ork is much snappier than in Vanilla or Pd-extended. But I haven't measured the cpu load.
