Hi again, As you said I had to modify some of the kernel buffers, rmem_default, wmem_default , rmem_max, wmem_max.
However, if I put them quite small, the routers start doing strange things. For example they start reporting 0% link usage when I am sending traffic, everything quite random... Does anyone know what could be the reason ? What could go wrong when the buffers are small ? Apart from packet loss.
