      Need your help to figure out why upload speed passing through pfSense guest is not exceeding 4mbps on a 1G internet link.
      I have a Centos 8 host with 2 network cards, 2 VMs: pfSense2.4.4 and ubuntu18.4

      Setup:

      ISP Router 192.168.2.1 --> Cisco SW Vlan 2 --> Centos8 BR0 192.168.2.241 (host NIC1) --> pfSense WAN NIC 192.168.2.242 (Source BR0 - Device model virtio)

      pfSense LAN NIC 192.168.5.242 (Source BR1 - Device model virtio) -->Centos8 BR1 192.168.5.241 (host NIC2) -->Cisco SW Vlan5

      Also on the same host running VM2 : Ubuntu 18.4 with 1x NIC on Vlan5
      Ubuntu LAN NIC 192.168.5.102 (Source BR1 - Device model virtio) -->Centos8 BR1 192.168.5.241 (host NIC2)

      Speed test:
      CentOS has 2 1GB NICs and ISP internet speed 1GB up/down

      Speed test from Centos -host
      Testing download speed: Download: 918.25 Mbit/s
      Testing upload speed: Upload: 710.98 Mbit/s

      Speed test from pfSense KVM Guest1
      Testing download speed: Download: 580.14 Mbit/s
      Testing upload speed: Upload: 501.42 Mbit/s

      Speed test from Ubuntu KVM Guest2
      Testing download speed: Download: 859.21 Mbit/s
      Testing upload speed: Upload: 4.06 Mbit/s

      Pfsense is on out of box configuration : DHCP for Lan
      Ubuntu is also out of box and DHCP client

      Tried changing the KVM Device model to e1000e and rebooted everything - did not work

      Any idea whats going on?

      Thanks in advance

        did you try iperf3 ? it may not be a kvm/ubuntu/pfsense problem

            iperf is working, try against some external services like
            iperf3 -4 -c bouygues.iperf.fr

            more servers here https://iperf.cc/

            speedtest script never worked for me.
