Hello @luhhiiz,
Selective Forwarding Unit is something you can configure and optimize for a better pixel streaming experience. Plus, performance bottlenecks on the server can be the reason for input lag during the stream as well.
Without SFU, because streaming will try to force your internet connection limits to increase the streaming quality, you may face some lags while using it. In addition to that, if you are far away from the server location, it might be another reason as well, physical distance to your server also matters.
If you don’t want to deal with SFU, or server orchestration, you can check Vagon Streams.
Our internally developed interactive streaming solution adapts itself according to the network conditions of your user by keeping 60FPS & 4K streaming quality, and we do the server/region orchestration process on behalf of you to serve your application from the closest server to your users.
If you need any assistance, I will be happy to help.
Best,
Serdar
