It'll be slower fetching content from the player than it was putting the content on the player. The fast-channel stuff implemented for v2.0 only works in one direction.

It shouldn't be that slow, though/

The fastest way to retrieve the content is by installing Hijack, and then using FTP, or the web front end. I believe that if you have Hijack installed, jemplode will use the FTP transport. emplode won't.
