Does anyone know why Skeinforge takes so freakin' long?

Does anyone know why Skeinforge takes so freakin’ long? Has anyone else gotten Slic3r to work with Solidoodle?

I have been using Slic3r since day one with my Solidoodle 2 without any issues. Slic3r doesn’t talk to the machine at all, it just converts the .STL files into G code. Then I use Pronterface to send the G code to the machine.

Use Repetier host, it talks to the printer plus it come with slic3r and skeinforge.
