Well, it is about bulk encryption and thus it is an I/O problem.
Today's general purpose CPUs are faster than average accelerators.

It should be possible to tune gpg for better performance for large
amounts of data. Increasing the internal buffers should help. gpg is a
general puspose tool and designed to work with a low memory footprint.
Another option would be to write a module for doing the bulk encryption
part in an optimized way.
Die Gedanken sind frei. Auschnahme regelt ein Bundeschgesetz.
