What can the interface 10 Gigabit*4 handle?
The only hard limitation I can see is the network interface which as you can see, your usage is far below what the interface can handle.
From tests such as this showing 10 GbE speeds of up to 900.6MB/s, would we then be able to multiply this by four and then assume this throuhput:
3,5 GB/s amounts to 28 Gbps, so the c3.8xlarge instance with its 10 Gigabit*4 should be possible to handle 25296 viewers each consuming 1166.6 Kbsp:
900.6 MB/s * 4 = 3,5 GB/s
This is insane. Please correct me.
25296 connections with an average bitrate of 1166.6 Kbps = 29510313,6 Kbps == 28.144 Gbps == 12665 Gig per hour
Edit: I just noticed that the *4 refers to a footnote and not that the instance has four 10 Gigabit interfaces.
So I should not multiple 900.6 MB/s with four. It's just 900.6 MB/s == 0.879 GB/s == 7.036 Gbps == 7377715 Kbps.
7377715 Kbps / 1166.6 Kbps = 6324 concurrent connections.
