I am looking for performance measurements in cycle counts for an implementation of the elliptic curve Diffie-Hellman for curve, ed25519. Ideally, the cycle counts should be for the M4, so that they are comparable with the pqm4 benchmarks: https://github.com/mupq/pqm4. Are there any measurements that can be compared to this end?

In general, I would be interested in how much "slower/faster" in terms of CPU cycles a elliptic curve Diffie-Hellman performs vs. say Kyber.
