      @muenchris Yes, in fact you won't be shaping your download speed at all, you just still need the rule to make the firewall happy. The only thing you'll be shaping is your upload speed (by up to 20%), which is just to stop the overload that seems to cause this. Let me know how you get on.

          @abtekk Quick question: I did not select any of my interfaces in the firewall rule. Do I have to select all interfaces that I use in my load-balancer gateway group or keep them all unselected?

            If I reboot the 6100 I do not see any lag for a day or so

            A day seems fast for my suggestion but check to see if it's running out of memory. pcscd has a memory leak.

            OTOH if the Internet pipe is full then that will back up everything and traffic shaping can help that a lot.

            Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
            When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

              @steveits My network setup is quite complicated. Behind the pfSense/6100 there is a Unifi UDM Pro that manages my main network that has 5 sub-networks (IoT, Cameras, Media, Gaming and Business). All firewall rules are managed by the UDM Pro - the pfSense is "only" load balancing. This results in my triple-NAT setup.
              Also my WLANs are all LTE router with non-consistent internet speeds (very different for time of day and day of week).
              Especially the (isolated) IoT network creates a lot of "mini-Connections" to their respective clouds.
              If there is a memory leak in one of the pfSense services it might be caused by the IoT network (over 150 devices).

              Is there something (like a specific service) I can "flush/restart" periodically? I would have to restart the complete Netgate every night

                According to this thread:

                https://forum.netgate.com/topic/112527/playing-with-fq_codel-in-2-4

                Codel has a bug. Use "taildrop" instead. You'll get same result

                    The pcscd service, as mentioned :) If you aren't using IPSec you can just stop it, though it will start when pfSense boots. Otherwise if you follow into that bug report there is a patch to disable it properly. Not saying this is your issue, but it's generally an issue on all installs eventually.

                      First I've heard of that. I don't see anything recent in that thread detailing it. A lot of people are running that.
                      Is there a bug report?

                        The thread is quite long. Here is the exact post. I think it's not Codel itself but pfsense:

                        https://forum.netgate.com/topic/112527/playing-with-fq_codel-in-2-4/770

                        You get this error:

                        "config_aqm Unable to configure flowset, flowset busy!" error.

                          Ah, OK. That's not a bug it's a feature. ๐Ÿ˜‰

                          I've never hit that but it looks like you would only ever hit it if trying to re-configure an existing pipe that is actively in use.
