Steve, you are correct, I was comparing Opus to my current production mix of G.711 and G.722. Here are more precise results on AWS M3.2xl instance with 8 CPUs for a 10 person conference with all clients connecting from Chrome via WebRTC. FS CPU usage was jumping more or less within these ranges throughout the conference: PCMU: 4.3% - 5.0% 722: 7.6% - 8.3% OPUS: 25% - 50% On Thu, Apr 7, 2016 at 9:04 PM, Steve Underwood <steveu@coppice.org> wrote:
You should be seeing a significant different between G.711 and G.722, so bundling them together doesn't make sense. G.711 takes only a minute amount of CPU effort. G.722 takes a significant amount.
Regards, Steve

In my tests OPUS transcoding seems to consume 5-6 times more CPU then G.711 or G.722.

I've seen estimates that opus is up to twice as heavy as g729. webrtc encryption adds some (although not huge) load on top of that. 20 opus sessions per cpu seems low, are these particularly slow processors or virtual processors?
