...I don't understand: why is Hash Suite 3.3's speed slightly higher than
the 23.7M you mentioned above?

23.7M is the speed of the full sha256 compress function. 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.

Regards,
Alain
