I think you'll need to be far specific.
If you want to know bulk AES128 performance, then maybe this will help:
https://csrc.nist.gov/csrc/media/events/lightweight-cryptography-workshop-2015/documents/presentations/session7-vincent.pdf
What compiler? What MHZ? What kind of RAM?
The above paper uses mbedTLS (which used to be PolarSSL, but ARM bought it).
The bulk rates are likely comparable. I don't have any data, but a google
searched found a variety of papers.
Fitting openssl into an M3's code space can be easy or hard depending on many factors.
If you are concerned about setup times, then what method are you using to authenticate?
(RSA? ECDSA? PSK? Raw Public Key)
