It calculates based on the Face "metric", which by default set to 1 for each Face (= incidentally, resulting in hop count).  If you update Face metric with latency related metric represented as an integert (unfortunately, we don't have anything that is already available; patches welcome), you will get latency-based calculation of routes.
