Hi,
I am trying to check the forwarding rate between two net devices on my
machine. What I see is that when the rate gets higher than some
thresohld, the reception rate can still increase but the trasnmit rate
reaches a maximum. At this point I assume packets get dropped. When
looking at the CPU utilization I see that they're around 50% so the
CPUs can do work. I also see that the trasmit queue is not stopped so
I think that maybe the IP layer drops them (lack of buffers?). Does
anyone have an idea?
