No, they were slower from the very beginning. If I remember correctly, there is comment about this somewhere. I just did not find any simple way to do 32 bit fixed point arithmetics scaling from bps to Gbps and was lazy to investigate this further, tables are much simpler and more flexible. > What about removing the RTAB system entirely? Well, if fixed point arithmetics is not a problem. Plus, remember, the function is not R*size, it is at least R*size+addend, to account for link overhead. Plus account for padding of small packets. Plus, when policing it should deaccount already added link headers, QoS counts only network payload.
