I have used the ippcp library to check out the performance of SM3 and SM4, and compared them with the lasted openssl version. The result is that the ippcp library did not perform much better than openssl. I compiled my test code with ippcp by using gcc, and I install IPP and IPPCP by default way. My CPU is i5-7400. So, did I use that in correct way? By the way, I found that the ippcp2017 perfrom better than ippcp2019. Waiting for your replay.
