I have been comparing X25519 (Curve25519) vs RSA for key exchange. X25519 is ~500x faster for key generation with 32-byte keys vs 256+ for RSA.

Anyone using ECIES pattern (X25519 + HKDF + AES-256-GCM) in production?

Generally you only do the key generation once. A 2048 bit RSA key takes only a second or two to generate these days.
