This has nothing to do with set.update, the difference is due to the time to setup the generator: $ python -m timeit -s 'x = set(range(10000)); y = []' 'x.update(y)' 1000000 loops, best of 3: 0.38 usec per loop $ python -m timeit -s 'x = set(range(10000)); y = (i for i in [])' 'x.update(y)' 1000000 loops, best of 3: 0.335 usec per loop
