      Hello,

      I'm new to pfSense and have been doing a lot of searching to see if my setup is suitable to take advantage of my Gigabit internet connection.

      When speedtesting with a direct Modem to PC connection I receive 850 to 950Mbps
      however with pFsense in-between I have never tested over 600Mbps

      Here is my setup.

      pfSense 2.4.3 virtualized with HyperV
      CPU: AMD Phenom II X6 1090T Processor (6 Cores assigned to VM)
      Memory: 8GB Total (2GB assigned to VM)
      NIC: HP NC364T PCIe 4Pt Gigabit Server Adptr
      NIC Config:
      1 Port dedicated as External Network Virtual Switch in Hyper-V for WAN
      1 Port dedicated as External Network Virtual Switch in Hyper-V for LAN

      Originally I was maxing out my speedtests at 500Mbps but after unchecking
      Hardware Checksum Offloading, Hardware TCP Segmentation Offloading, Hardware Large Receive Offloading
      I was able to achieve 600Mbps

      Also running iperf with pfSense as the server mimics the speedtest results.

      I feel like my hardware should be sufficient to achieve gigabit speeds and I am just missing some simple configuration.

      Any help would be greatly appreciated, Thanks!
