    I am getting very slow speeds with PIA VPN enabled even with AES-NI. Its like pfsense is not taking advantage of AES-NI support that my hardware has.

    My cable is a 100Mbps down / 10Mbps up.
    But with my PIA VPN enabled I only get 40Mbps down.
    If I use the PIA app on windows I get very close to 100Mbps down.

    I assumed that this hardware below was sufficient at handling these speeds with VPN and the AES-NI.

    Any help would be greatly appreciated.

    2.4.3-RELEASE (amd64)
    Intel(R) Celeron(R) CPU N3150 @ 1.60GHz
    4 CPUs: 1 package(s) x 4 core(s)
    AES-NI CPU Crypto: Yes (active)

    Followed these instructions to set it up.

        This fixed my speed issues.

        In your open vpn client settings I added this to my custom options.
        My speeds went from 40Mbps, to 90Mbps.
        My ping times also went from 27ms to 20ms
        This was recommended from this thread. https://forum.netgate.com/topic/114212/aes-ni-cryptodev-openvpn-help-a-n00b-understand/23
