This is classical due to the burst size being too small, so TCP goes into 
saw-tooth mode (slow-start, quickly rises in speed, hits rate-limiter that 
drops multiple packets, goes back into slow-start, repeat forever).

I don't have access to any Summit200 so I don't know if the burst size can 
be increased, but if it can you should try that.
