I've heard people talk about ed25519, though I'm not sure it can be used for encryption. Doing ECDH with our curve is within a factor of ~2 of the fastest encryption available at this security level, AFAIK. And separate encryption would ~double the amount of data vs using the ephemeral key for derivation. Using another cryptosystem would mandate carry around additional code for a fast implementation of that cryptosystem, which wouldn't be fantastic. So I'm not sure much can be improved there.
