For RSA operations, which are costly and fixed-size, it's an obvious win.
If you can do it a non-blocking mode, it also free's up the main CPU to go
do more "real work." But even if not, it's possible to drive cards like
the Cavium Nitrox to a couple of thousand RSA connections per second. It's
hard to have a commodity CPU do that and have any cycles for anything
else.
