Batching makes a huge difference. As an example, I made a prototype for a platformer game. I started without using batches, and the program was running under 60fps after a few sprites already. Batching them up made a difference right away giving 200fps, which it was the same as not drawing any sprites at all.
Primitives can be batches just as easily. Read the programmers guide on the pyglet.org site if you haven't already, and if you have, I suggest you read it again ;). Specifically the vertex lists and such, and check out the API on the pyglet.graphics module as well.
