Comparing the run_time between insertion sort and quicksort shows insertion sort gives better performance when the given data sequence is in ascending order. For the nearly sorted list, whether insertion sort performs better than quicksort depends on the size of the list and the number of randomly ordered items. Compared to the insertion sort, the results show quicksort yields shorter run_time if the list is in descending or random order. The main drawback of quicksort is the worst case behavior of O(n2) comparisons when the list is in ascending or descending order. It has been shown that quicksort also performs poorly for nearly sorted list.
