    Full gigabyte for a few minutes then drop to ~20MB/s

    Have to restart networking to regain 1Gbps

    What could cause this ? This is on a Proxmox KVM VPS running Centos 7 or Ubuntu 17

    Sure looks like traffic shaping.

    I should say I cannot reproduce the problem on the node itself.

  • Possibly VM running out of ram to cache the download and having slow disk access?

    Try saving to /dev/null instead.

    So it seems that the Virtio drivers are at fault...

    Yes. The less-overhead not-as-deeply-emulated drivers are obviously to blame.
