bpo-35513, unittest: TextTestRunner uses time.perf_counter() (GH-11180)
...
TextTestRunner of unittest.runner now uses time.perf_counter() rather
than time.time() to measure the execution time of a test: time.time()
can go backwards, whereas time.perf_counter() is monotonic.
Similar change made in libregrtest, pprint and random.

Hoist the float conversion out of the inner loop. (GH-10430)
...
Currently, the *n* and *total* variables get converted to floats each time they are multiplied by random(). This minor tweak does the conversion just once and gets a small speedup (approx 3%).
