The original question was from 2010, so answering Brad new update, and consequently 2010 question. :P
I can provide a theoretical answer, but you will have to test in practice and compare the speed.
From a TMM point of view, a local datagroup and an external datagroup should be the same, they should both be cached (not sure if in each TMM, or MCPD). So, the speed should be the same.
