GRO will only trigger for HTTP, WebSocket and TURN traffic, I believe; most of Gal=C3=A8ne's traffic is RTP over UDP, with packets under 1200 by= tes. We just had a meeting with 70 people and at around 40 cameras switched on= , Gal=C3=A8ne became unusable =E2=80=94 there were too many voice drops, wh= ich indicates two issues: * I need to think of a better way of prioritising voice over video when under load; * there are fairness issues =E2=80=94 some clients were receiving okay-= ish audio, others were not. =20 Gal=C3=A8ne recovered after some people switched their cameras off, I did= n't need to restart anything. At the highest point, Gal=C3=A8ne was at 270% = CPU, and the TURN server was using another 50%. That's on a four-core VM. > On the other hand, gro is saves on context switches in vms. $ PRODUCT INSTALL GALENE /CONFIGURATION=3DDEFAULT /LOG -- Juliusz
