RatedSource userlevel high CPU #435

I wrote a simple rated traffic generation using RatedSource element. The click config generated 100KBps UDP traffic. When I ran that in userlevel the single core CPU ran at 100% until that packet generation LIMIT was reached. Is this normal? How can I optimize for traffic generation?

What is the downstream pull to push element ? If it does not support notifications it will pull endlessly.

Pull Element. Which downstream element you can recommend to achieve high data rate traffic stimulation?
