      DSLReports does an HTTP ping via websockets. If you're doing a normal ICMP ping, then your traffic shaping may be placing ICMP into a different queue. Bufferbloat is a per-queue characteristic. Make sure you're measuring the same queue.

        Thank you  for your  response (was hoping to get a response from you). I was doing a normal ICMP ping, ping google.com in cmd, so  should I test dsl reports again and see what q  is used when its testing? Thanks

            So for my config, I really do a pretty simple config as I have FIOS I'm on 300/300.

            I break up WAN/LAN into 3 queues (High/Med/Low) and do 100/100/90 for bandwidth respectively. I only use CODEL on each queue that is setup.

            My rules prioritize my ICMP and my XBox traffic. I deprioritize my 'other' plex server traffic and everything else falls in the default queue.

            I use 'quick' floating pass rules so I can see what states are captured in each rule and in each queue.

            I've tested a lot of downloads and uploads maxing each side of the connection. My biggest problem up to this point was not getting the size of the WAN/LAN config and really making sure I was at the minimum bandwidth I can expect and really a little lower. You sacrifice a bit of your pipe to ensure throughput.

              Try without shaper and with shaper. Also try to limit bandwidth to the half of initial to find out is there a difference.
              I have similar shaper setup like Animosity022 have, but also using limiters to equalize bandwidth for all users.
              Bandwidth limits in shaper and limiters are set to 90% of real tested bandwidth, because I have had buffer bloat problem on ISP side, I have gigabit ethernet with 300/300 PPPoE and on Sunday evening it's common problem.

                Hi w0w Great to hear from you. I tried with shaper also and also tried giving half my bandwidth speed but same results.

                    To make sure that your shaper works, also please check status -> queues, under heavy load you will see drops, Animosity022 showed it on screenshot. I think it works, just because your manual ping test shows it.
                    As for dslreports, it looks like your bandwidth is 10 times less then you have said in the first post. I think there is the problem just with dslreports tests or some ISP limits that just don't let the test to run correctly, you can ask your ISP tech support.

                      The shaper works fine as I get drops and In my manual test turning off traffic shaping pings went up to 500ms turning back on shaper pings back down to 24ms, there is nothing wrong in pfsense in DSLReports there is something  funny, I called my isp and  we did some test they also told me that my pings are great under load they think that there is something wrong with the sites test or pings to the servers it is pinging. Also I tried a router with firmware DDWRT  with qos and same results, and something also is not right in my results I sometimes just get  ( - ) no letter  I also get this in the speed results

So same ISP different quality

                            I think ISP fixed something.
