Hadi, I'm not sure that the AppEngine hub as polling in it, but if it does it's probably not a great solution of high frequency feeds. I have no idea what you should expect, but generally, PubSubHubbub is not *black magic*. If you don't use it in the way it's supposed to work, it's unlikely that you'll get the results you're expecting!
good luck.
