How big are your buffers (preferrably answer would be in milliseconds)? 
What access speeds are you providing?

It's standard behavior for network traffic to sometimes be at higher 
speeds than the customer access speeds, the sender only knows about 
congestion if there is an increase in RTT or if there is packet loss (or 
in case of ECN, EC=1 flag), and the only way to find out is to probe (=run 
faster than customer access speed).
