      How to use modern Congestion Control (CC) transmission protocols BBR2, QUIC, RACK into pfSense ?

      Or we just need to waiting until FreeBSD developers implement this CC protocols ?

      P.S. Even most of iperf3/iperf servers from this official worldwide list, using BBR/CDG

        Good News!

        HowTo enable BBR in FreeBSD

        Anyway, only CDG CC is better than any other in pfSense / FreeBSD 12.2... (and this list THE SAME AT LEAST 8+ YEARS!!!!)

        ls -l /boot/kernel/cc_*
        
        /boot/kernel/cc_cdg.ko
        /boot/kernel/cc_chd.ko
        /boot/kernel/cc_cubic.ko
        /boot/kernel/cc_dctcp.ko
        /boot/kernel/cc_hd.ko

              Thank You for help.

              After some declined requests, I am become to a little skeptics about reasonable (on my opinion) features added to pfSense.
              But slowly industry pressure make this for me :) Just a little waiting...

              BTW, I am a newbie in FreeBSD, so is possible to recompile pfSense CE code with ALL THREE options?
              Or, because the modification of TCP/UDP stack are deeply underground, we able to choose only one of them (mean BBR2/BBR or QUIC or RACK) ?

                I think it's a good idea to create a feature request now. At least it will be traceable.

                About recompiling... since FreeBSD 13 uses a lot of new code it is definitely takes some time to make everything work even at Netgate level. I am not newbie in FreeBSD but compiling an own version of pfSense is beyond my capabilities.

                  Just done.

                  BTW, I love the pfSense and would be happy if pfSense's product would be best on the market, and of course have all needed features on our “mobile devices world” era.
                  And not sitting with cubic next 7+ years and waiting...

                    Are you sure that https://www.reddit.com/r/PFSENSE/comments/ajs0qy/quic_protocol/ is really useful? ;)

                      On what You skeptics based on?

                      At the first: I Googling about negative experience with this method and find no any. Please point me to if I am wrong.

                      I have no such knowledge right now to recompile FreeBSD or pfSense CE with QUIC support, so may be someone doing this and give me results for testing?

                          Recently has a time to read more about BBR implementation progress. Very impressive. Just take a look on graphics “quick vs bbr”

                            Is any news about enabling QUIC in pfSense CE at the end of 2023?

                            Because around 90% of traffic in the world come to/from mobile gadgets, but we still using old congestion protocols in pfSense (even QUIC available in FreeBSD in that pfSense based, since several years…)
