It probably depends more on your network speed. If you have a slow network, then run pg_dump on the machine where the database lives and use compression (--format=c) and restore using pg_restore. It will cut WAY down on the amount of data that has to move across the net. If you have a fast network, then it doesn't matter very much -- you'll be limited by disk speed.
