      @occamsrazor Jimp did a quick bit on codel during the last Hangout, with a config example.

      https://www.youtube.com/watch?v=o8nL81DzTlU&t=380

      Thanks. That's a nice and easy guide. I followed all the steps but wondering if I've done something wrong as the results are inferior to without. I'm on a 50MB dsl connection and before this got this result:

      <a href="http://www.dslreports.com/speedtest/39052963"><img src="http://www.dslreports.com/speedtest/39052963.png"></a>

      I had an A and A+ score so maybe the traffic shaper is not even needed. After enabling the shaper as per the video with WANDown bandwidth set to 50MB and WanUp set to 40MB, I get this:

      <a href="http://www.dslreports.com/speedtest/39053743"><img src="http://www.dslreports.com/speedtest/39053743.png"></a>

      My bufferbloat score is way worse as is my bandwidth. One thing I notice, when I go to PFSense > Status > Queues it says "Traffic shaping is not configured." - is that normal for this traffic shaping method?

          Thanks, output is:

          ipfw: bad command `shed'
          

          I set up the two limiters as in the video:

          0_1537256451183_Screen Shot 2018-09-18 at 10.39.21.jpg

          And the rule in the Firewall Floating tab:

          0_1537256567789_Screen Shot 2018-09-18 at 10.41.45.jpg

          Is there supposed to be something showing in the queues tab?

                sorry for the typo, when you run the dslspeedtest you should see in this output if fq_codel is active, which from here it seems like it is.

                  @mattund I watched the video linked before and end up with more question then before. Do we use masks or not. ? Do we use ECN or not, i remember on the upload side we should not use ECN.

                    Is fq_codel adaptive to bandwidth in some way? I'm wondering what to put for the WAN bandwidth values in the limiter, as my speeds can sometimes vary during the day.

                    Also, I am running pfBlocker developer version. Should the fq_codel floating rule be above or below all the pfb rules?

                      The pfb rules are block/reject so it should not matter. This should only apply on pass/match rules depending on what You are trying to achieve.

                      ps. - I don't thin fq_codel is adaptive bandwidth. Normally I set it to 90% link speed a peak hours(like 8-9PM) in the evening.

                        @occamsrazor Conventional wisdom says to measure your WAN link speed several times throughout the week, at various times of the day, and then use 90-95% of your LOWEST value.

                          @kom Thanks. I was doing some testing last night with the fq_codel download bandwidth set to 50Mbit, and when I was running a popular torrent I hit a sustained download rate of over 100Mbit. So it would seem to me that this "limit" isn't actually a hard limit. Can that be right? Or does fq_codel only affect TCP traffic (my torrent client is set to use uTP)

                            @occamsrazor I have no idea. I'm fairly dumb when it comes to QoS, and know just enough to be dangerous. I haven't played with codel at all.

                              you should not be able to achieve a higher rate than htb (hfsc?) specifies. There are a lot of ways to configure htb wrong (like not classifying all packets correctly), there have also been bugs in some versions.

                              Your initial result (2mbits!?) implied to me you'd got the kbit or mbit setting wrong.

                              The oddity of your current result implies you are putting utp traffic into another bin entirely. try to build the simplest possible thing that feeds all packets into a single fq_codel instance. Post your code.

                              The fq part of fq codel works on all packets, the codel part works well on anything that is tcp-friendly, which certainly includes utp and quic.

                              I don't know enough about bsd to help, we found trying to configure this stuff in the linux sqm-scripts so painful that we ended up replacing it all with the one-liner that is sch_cake.

                                What is HTB? And my understanding is with fq_codel we are not using HFSC? I followed the video so I have the WANDown and WANup limiters under the limiters section, but when I click on "By Interface" > "WAN" I don't have anything enabled in that section, and nothing in the "By Queue" section....... should I?

                                Post your code.

                                I'm doing it all through the GUI. Is there a command to show the configuration easily?

                                  What you folk are calling a limiter, I call a shaper. The two most common algorithms are token bucket and hfsc. google 'em. I have no idea which or an alternative are being used in the "limiter" concept here (?), nor do I have any idea how this gui is configured, I'm hoping others that are more familiar with bsd and pfsense can chime in. I'm just the co-founder of the bufferbloat project and care deeply seeing about seeing rfc8290 get deployed properly everywhere.

                                  I do think you need to enable things on the wan and queue sections but all I can point to at the moment is how to set up "sqm" properly on things like openwrt. Perhaps one of those tutorials would help in creating an analogy for this OS?

                                  https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm

                                      Remember to flush firewall states between each test.

                                      EDIT: what is your hardware and what packages do you use?

                                        Hardware is SG-3100 and packages are Avahi, nut, openvpn client export, and pfblockerng. So, not a lot. Overall the network is great, the only time I see the score is testing. I'm just saying my score is better with codelq than fq-codel after following the video guide. I reset states between testing.

                                          @gsmornot your post was fq_codel both times... Does your bandwidth change vs a vs codelq? If you are running out of cpu...

                                            Hello!

                                            I want to priorize two things:

                                            1. video-livestream (one server in my DMZ)
                                            2. VoIP
                                              So thats guaranteed that these to applications always have enough bandwidth.
                                              -> If the videostream need all, give them all (expect some 100kbit for the telephones).

                                            How can I reach this goal with fq_codel in 2.4.4?

                                            I already did the setup which was shown in the youtube-video/hangout with the effect, that the download is now around 175Mbit and the upload only 170KBit! (my cable line is around 220 down, 20Mbit up)
