Comment (by jmantysalo):

 Timings depend on test set. But with all 7-element posets this seems to be
 about 10-times faster. On the other hand, when testing with 7-element
 posets that really are duals this runs about 10% slower.

 How should this kind of codes be tested, what kind of random posets to
 use?
