I'm not really sure what kinds of figures to expect here, since this
is just one part in the overall processor load. Typically I get ~0.15ms
on an Intel Core 2 [email protected], which looks plausible to me:
DMX frame interval is 1/44Hz =~ 23ms. Applying GM to ALL channels takes
less than 1ms so there's a full 22ms to spare after GM. */
