Cant say anything certain on this one. I do know that not all the messages are sent to the other side. There are optimizations
in place, using the Dovecot transaction logs and some pretty complicated application login, but a lot of data still needs to be
processed by the dsync "brains".

I think testing with your particular setup and data would give the most accurate results.
