IIRC AES GCM does about 40-70 MB/s per core on Pi4, and ChaPoly does 150-200MB/s. On Pi5 AES GCM does 1.5-2GB/s per core, and ChaPoly is still something like 1

IIRC AES GCM does about 40-70 MB/s per core on Pi4, and ChaPoly does 150-200MB/s. On Pi5 AES GCM does 1.5-2GB/s per core, and ChaPoly is still something like 150-300MB/s. You can do experiments yourself with `openssl speed`.
