Are your results written up anywhere? It would be great to see more details of the comparison and the actual numbers. Unfortunately, I don't think that DTLS 1.2 is the best comparison -- DTLS 1.3 should be seen as the current "state of the art" for DTLS, and is expected to itself be leaner than DTLS 1.2, which might wash out some of the results you've seen here.
