Scalability Of JANUS

[Janus_SFU]

Hi lorenzo,

I am using JANUS to build a conference room.I am using the plugins provided and apart from that adding chat and document sharing 

features to it.I want to know the scalability of JANUS as to how many concurrent calls it can handle. On a 

• CPU: 

  6 vCores

• RAM: 

  6 GB Guaranteed

• HDD: 400 GB

VPS server,I tested out around 40 video calls and it was working well.So may I know how it fares when it comes to heavy load testing as you 

guys must have done.Any reports or stats can help my cause.

Thanks

There's a paper that describes a few things on performance here:

https://janus.conf.meetecho.com/citeus

It's from last year, though, and several things have been optimized and improved in the meanwhile. Besides, we didn't push it to the top in all scenarios due to lack of resources. Just to do a quick summary, in general we found out that CPU/mem usage was minimal, and the real bottleneck was bandwidth usage.

Should you make more tests on your own and be willing to share the results, that would be great.

Hi Lorenzo,

Thanks for the reply.Can you suggest some ideas to improve the bandwidth bottleneck?
Thanks

[Lorenzo Miniero]

Yeah, buy more bandwidth from your service provider :-)

Or use multiple Janus instances on different servers, each with its own dedicated bandwidth.

Trying to force a lower bitrate on all active sources can also help in that sense, as this means all viewers will also require less as a consequence.

Hi Lorenzo,

I was wondering if you can give me some details about the scalability of Janus.

In the scenario with multiple instances of janus in multiple machines:

Are them somehow "connected" and talks to each other or I have to make a logic to redirect my traffic of one room in the same server?

In a few words: is it horizontaly scalable?

Thanks!

I'll share some info on this in a few weeks: https://commcon.xyz/speakers/lorenzo-miniero/
