The representative performance specifications below are results averaged over many repetitions of each function call. Data is in cache. Results were measured using a 150MHz Pentium processor PC with a 256K second level cache and a 150 MHz Pentium with MMX processor PC with a 256K second level cache. The tests were run under Windows* 95.
