The Boyer-Moore algorithm is used to implement fast substring search. The algorithm has some overhead caused by filling a table. Substring search then requires at most 1 / substring-length less string comparisons. On modern desktop hardware, Boyer-Moore algorithm is seldom faster than the naive implementation if the searched substring is shorter than the cache line.
