NoOp, the new Ghostscript version would be a too high impact for an SRU, but the adding of "-dNOINTERPOLATE", at least for very common drivers and filters would be possible. You could try it out, at least if it is currently a Ghostscript process which slows down your printing (check with "top"). Can you find out which filter (and whether it is Poppler or Ghostscript) is the culprit for you now?
