      Here is what I have. I don't know how to interpret this. Lots of errors:
      dev.ix.0.mac_stats.rec_len_errs: 20
      dev.ix.0.mac_stats.remote_faults: 0
      dev.ix.0.mac_stats.local_faults: 53

        Mmm, interesting no one type....

        Check netstat -m make sure there's no buffer exhaustion happening.

            Hi @aholmes5

            I have the same issue. I connect my Fiber WAN on SFP+ 10G on netgate 6100 with a 10GTEK sfp+10G and my unifi switch on the second WAN on SFP+ 10G on netgate 6100 with DAC 10G cable but my download speed is reduce of 80% but my upload is fine.
            Do you found a solution ?

              Are you seeing errors on the interfaces?

              Do you have any traffic shaping?

                    No errors shown there. So some on the WAN?

                    How are you testing the throughput?

                        Hmm, not really a significant number there. Nothing that would cause throttling to that extent.

                        What about the PPPoE parent interface? Which I assume is ix0?
                        Try: netstat -i and ifconfig -v ix0
