Hash Suite uses many optimizations, including the calculation of the last 8 steps only when needed (very unlikely). It also executes other code, like the key generation. In this case the optimizations outweigh the cost of the additional code. ...If it's for 4 cores vs. 1 core, then why is so much overhead incurred (almost 4x)? Only 1 core. For 4 cores is 93.3M.
