Понимаю, что топик стар как мир, однако хотел спросить.
почему результирующее время такое огромное становится?

вот пример:

>>> list1 = [7, 2, 3, 10, 12]
>>> list2 = [-1, 1, -5, 4, 6]
>>> from timeit import timeit as ti
>>> ti('map(lambda x, y: x*y, list1, list2)', 'from __main__ import list1, list2')
8.450500659762035
>>> ti('map(lambda x, y: x*y, list1, list2)', 'from __main__ import list1, list2')
8.715931700531947

list1 = [7, 2, 3, 10, 12]
list2 = [-1, 1, -5, 4, 6]
from timeit import timeit as ti
ti('map(lambda x, y: x*y, list1, list2)', 'from __main__ import list1, list2', number=1)
