You should make sure that there are no caching effects here. Your operating system may have loaded the file into memory (assuming that you have enough of that) after the first read and then served it from there when you ran the second benchmark. So, make sure you measure the time twice for both, preferably running both benchmarks in reverse order the second time. That being said, it's not impossible that f.readlines() is faster than line-wise iteration, because it knows right from the start that it will read the entire file, so it can optimise for it (didn't check if it actually does, this might have changed in Py3.3, for example).
