You can use iputils ping to generate streams and bursts, but it''s not 
perfect - still useful, but you need to check with rate estimators/ 
tcpdump timestamps on a different box what is happening.

ping -l 10 -i 0.02 ....... will burst 10 then do 50pps. For me it goes a 
few pps slow if I run 5 instances + 5 netperfs.
