Comment(by was):
Answering my question, on my computer with your code:
{{{
sage: M = S.random_element(1,10^8)
sage: timeit('M.det();M._clear_cache()')
625 loops, best of 3: 8.82 µs per loop
sage:
sage: M = S.random_element(1,10^10)
sage: timeit('M.det();M._clear_cache()')
625 loops, best of 3: 9.86 µs per loop
sage: M = S.random_element(1,10^200)
sage: timeit('M.det();M._clear_cache()')
625 loops, best of 3: 49.8 µs per loop
sage: M = S.random_element(1,10^300)
sage: timeit('M.det();M._clear_cache()')
625 loops, best of 3: 92.2 µs per loop
sage: M = S.random_element(1,10^1000)
sage: timeit('M.det();M._clear_cache()')
625 loops, best of 3: 585 µs per loop
}}}
