    There is a hidden setting in Tomato 1.18 and above, that should improve QoS performance for P2P traffic or large numbers of connections (more than 1000). It changes the QoS qdiscs from SFQ to PFIFO, which use less CPU and scales better to large numbers of connections.



    This is how to apply it.



    1. Telnet to your Tomato router.



    2. Enter the following commands:

    # nvram set qos_pfifo=1

    # nvram commit



    3. Reboot your router or restart QoS to make the change take effect.



    4. To check if the change was effective:

    # tc -s qdisc show

    5. If you want to remove the change, issue the following commands then reboot the router or restart QoS.

    # nvram unset qos_pfifo

    # nvram commit
