that's mainly a gpg issue. gpg does not support multithreading and
probably never will. you can search the web about the why.

to implement what your asking in duplicity we would have to create
volumes in temp space and only thereafter encrypt them in parallel. the
current design however is to stream all data and cutting chunks whenever
the volume size is reached. this way no extra temp space is used but yes
it is not possible to parallelize as well.
