Hi, but even then you can try to optimize a bit with net-aggregate, if you haven't yet already done so, try to increase cam-size etc. To my understanding everything that can be "switched" (routed) with information from CAM is quite fast and I *think* that 1GBit or more should be possible. But this is not based on practical experience with that small packets you have. Regards, Stefan
