Comment (by jmantysalo):
I tested with a list of all non-isomorphic posets of 8 elements. There are
16999 of those.
Before the patch it took 0,69 seconds to run my test code for the first
time. Second run took 0,39 seconds. After the patch timings were 0,70 and
0,41 second. So this will take something like 15 ms for 15000 posets, i.e.
a microsecond per poset. (At i5-3470 CPU @ 3.20GHz).
I think that this in not too much penalty for better usability.
