Slow WAN download speed



  • Hello all,
    I have slow download speed on my pfSense firewall installed on an XenServer 6.5 in a OVH datacenter: 10 MBps down and 80 Mbps on up.

    If I download a test packet from the pfSense shell I reach 10 MBps, if I download the same packet from the hypervisor I reach 25.3Mbps.

    I have disabled hardware TCP segmentation offload and hardware large receive offload, the routes look ok.

    Da you have any suggestion on how to debug it?

    Best regards,
    Ivo



  • Hello everybody,

    I fix it as shown in this article: https://forum.pfsense.org/index.php?topic=85797.0

    The download speed from the pfsense console doesn't rise, but the virtual machine placed behind it can now download at full speed.
    So do not trust the speed shown by the fetch command :-)

    Have a nice day,
    Ivo
