Mismatch index is currently being checked by a brute force iteration over the buffer. Instead, break the comparison into O(sqrt(n)) number of chunks, with the chunk size of this order only, where n is the size of the buffer. Do a brute-force iteration to print to stdout only when the highly optimized memcmp() library function returns a mismatch in the chunk. The time complexity of this algorithm is O(sqrt(n)) * t, where t is the time taken by memcmp(); for our test conditions, it is safe to assume t to be small.
