GRO will only trigger for HTTP, WebSocket and TURN traffic, I believe;
most of Galène's traffic is RTP over UDP, with packets under 1200 bytes.

We just had a meeting with 70 people and at around 40 cameras switched on,
Galène became unusable — there were too many voice drops, which indicates
two issues:

  * I need to think of a better way of prioritising voice over video when
    under load;
  * there are fairness issues — some clients were receiving okay-ish
    audio, others were not.
  
Galène recovered after some people switched their cameras off, I didn't
need to restart anything.  At the highest point, Galène was at 270% CPU,
and the TURN server was using another 50%.  That's on a four-core VM.
