Thank you Pedro for the explanations.

Almost, there is lots of free memory, zero disk I/O and the host provider is asserting that there is enough Internet bandwidth behind the server. Any thing else to check? As I mentioned I’m using **htop** for monitoring. Does anyone know a better tools?

No! I thought it will increase the process on the server! So I will test it in our next webinar, probably tomorrow, and will share the result here. Just there is no clarification about `numSpatialLayers`. Please let me know what number best fits for my scenario?

BTW is **simulcast** available in v2 release? Not in the [release notes](http://discourse.lynckia.com/t/new-release-v2/423).
