      I recently got gigabit internet, and when connected to the modem directly I get 950mbit/s. However, when I have pfsense as the router, I get around 350mbit/s. I have tested all the cables and switches in between, and the only bottleneck I've found is the pfsense box.

      I did all the tests advised on Low Throughput Troubleshooting guide. Aside from ruling out the possibility that it was some other device, what I did find out is the idle CPU usage drops down to 28% when I reload fast.com 3 times in a row. Here it is at peak usage:

      I'm using two of the Intel PWLA8391GT PRO/1000 GT PCI Network Adapter for WAN and LAN. I have no traffic shaping or limiters or other CPU things going on that I could think of that would impact performance.

      I do notice I do get some CPU usage spikes on the main page, even when I'm not doing anything on the internet. Also, whenever I disable the WAN, then enable the WAN, or restart the modem, the CPU usage gets really high and the router setup page becomes unresponsive.

      Specs:

      System pfSense
      Serial: dc132d55-e5e8-11e7-a6b3-001b21482275

        The 45% interrupt time isn't good.  Smells like hardware to me.

            I just found out it's a Dimension 4550. I had to look up a YouTube video on how to open it (lol) since it's been years.

            Here is a picture of the inside. Blue cable is WAN, white cable is LAN.

                I have a Lenovo Ideacentre k410 that I could use, with the following specs for PCI:

                Specs
                Expansion Slots:
                1 (total) / 0 (free) x PCIe 2.0 x16 - half-length, full-height
                3 (total) / 2 (free) x PCIe 2.0 x1 - half-length, full-height

                Would that be enough?

                  PCIe is HUGE difference… old at 2.0 and x1 but still 500MB/s. way better than your pci bus..
