evolve: cache marker encoding to avoid performance degradation The main overhead in bug 4518 is caused by calculating relevant markers and encoding markers into the correct format. Calculating relevant markers takes (worst case) ~ 0.12 seconds. Encoding markers takes (worst case) ~ 0.06 seconds. Caching encoded markers takes care of the second part and speeds up cloning in bug 4518 by about 35%.
