The old Largest Buffer search algorithm is using Binary Search algorithm to find last successful memory allocation. But each successful memory allocation takes times. Since the unsuccessful memory allocation returns very quick. Changing the search algorithm to find first successful memory allocation starting from MAX, each testing step with granularity interval will speed up this test.
