Correct, the performance is not good and the only benefit of using it is if you need to offload crypto because your CPU is constrained (and don't care about the crypto performance).

Thanks! Hi, I couldn't find any information about the license, but I played around with this hardware crypto on some devices a while ago and found that they are performing terrible :) Much worse than the CPU.
