      Hi,

      I read in the docs the following:

      Another item to check is under System > Advanced on the Networking tab. Ensure that the boxes are checked for Disable hardware TCP segmentation offload and Disable hardware large receive offload.
      Regarding LRO there is an explanation- some drivers are broken. Well, could we get a list of driver which are broken?

      Regarding TCP segmentation offload- why is it considered to be faster when this is DISabled?

      I just do not understand why offloading tasks to hardware should slow down processing....

      Thanks for explaining me!

        It's explained in the doc that covers the page where the settings are:

        https://docs.netgate.com/pfsense/en/latest/config/advanced-networking.html#hardware-tcp-segmentation-offloading

        https://docs.netgate.com/pfsense/en/latest/config/advanced-networking.html#hardware-large-receive-offloading

        tl;dr they are faster if you are an endpoint but slower when acting as a router/firewall.
