How to performance test the Janus Streaming Plugin?

Hello i’m trying to test the performance of a Janus gateway using the Streaming plugin.

But I think this is not the best way to test for performance because I don’t get the results I think to get.

How is the Streaming Plugin tested on performance?
Is there a better way to test Janus?

I made a presentation on WebRTC load testing some time ago:

It’s a bit old, but some of the pointers may still help you. We personally use Jattack for that.
