needed cpu for HLS stream

[Alexander Zhilko]

what is the needed cpu for HLS stream, no transcoding at all .

only distribute hls stream.

what perfomance i can expect from 1cpu 2gb ram VPS , is it better to have less more powerfull VPS or alot weak ones?

Could you elaborate your needs if possible? 

Are you going to publish WebRTC and watch HLS?

Here is the table:

4 CPU   - Publisher 50   - Viewer 200

8 CPU   - Publisher 100 - Viewer 400

16 CPU - Publisher 200 - Viewer 800

32 CPU - Publisher 400 - Viewer 2000

If you have 1 core cpu, you can divide it to 4 which means it is either 12-13 publisher or 50 viewers.

rtmp / hls streaming and watch hls . 

the default LiveApp sending from OBS or ATEM hardware .

what's the cpu / ram requirments .

webrtc watch and webrtc stream requerments is what i seeks for .

also youre tabel doesn't have ram - 2cpu cores and 2GB ram would be sufficent for 100 watchers? or i need more ram where is the bottle neck and what is the constrain?

i thinking of the most efficient way to create a cluster , if our cloud solutions can provide per vps bandwidth of 300-500 mbps the most efficient would be to have 2-4 CPU instances according to your table .

and just spin up more instances as needed.

The table i sent is for webrtc publish-webrtc view. We don't have numbers for HLS but HLS view is much more easier on hardware than webrtc view. So, you can expect more viewers when watching in HLS.

I think if you think you will have a limited number of viewers, ex.300-400, i suggest using one instance which is more capable. 8 core machine would be sufficient in that case.

Also i don't think 2gb ram would be sufficient since also OS is going to consume memory and you won't have left much for software itself. I suggest minimum 4gb of ram.
