No that is really slow. Many normal working setups, mine included, run around 500 pps so you would get 50K in just a few minutes or maybe even less time.
Assuming this is YOUR AP why not cheat and take the easy road to confirm your setup is working. For now until you see your hardware working properly, go ahead and connect an associated client (such as your laptop or similar) and communicate between the router (AP) and the laptop. This will create the packets/traffic aireplay can use to fire off and start pumping IV's at blazing speeds. We can discuss how to approach AP's without associated traffic later. For now do what I suggest to verify your setup works properly.
If this works, and I bet it does, then you continue the learning curve from there.
