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? -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
