Hey Vince, Jakob and Davi! Thank you very much for your help, I received this suggestion below from an artist called tfox, I hope it is useful for you, I believe it is similar what you suggested me. It tooks only 0.047 seconds for 100K polygons.
*def buildFaceVertList(fnMesh):* * cursor, out = 0, []* * counts, idxs = fnMesh.getVertices()* * for i, count in enumerate(counts):* * out.append(idxs[cursor: cursor + count])* * cursor += count* * return out* thank you very much also to my buddy Marcus for trying to understand the question!
