It's not slow for AES though.

That was the example of slowest performance for this, in a full functional test -
where the application is in production configuration. That is, it does everything
from certificate verification to AES-GCM crypto, all in software on a few year
old hardware with encryption and decryption running in parallel.

With AES-GCM done in hardware (e.g. AES-NI) on a multi core CPU, the test shouldn't
take more than 10-15 minutes.
