[Icecast] Unable to utilize past 1 gbps

[Marius Flage]

I don't know if any such limitation exists, but maxing out just shy of 1Gbps sounds a bit more like an interface's line speed limited/set to 1Gbps somewhere in your production chain? You wrote that you have tested the bw - what did you use? Iperf? Speedtest?Maybe consider scaling with additional Icecast servers and use a load balancer in front? And then just scale accordingly? This sounds like an interesting challenge. Which radio station is this, if I may ask?--MariusSendt fra min Galaxy

The line bandwidth is tested and available. The web radio is hosted on a Proxmox virtual environment. We own the physical server itself and made sure to have allocated the sufficient amount of resources on the virtual machine.We found that no matter what we do overall upload cannot go over 1 gbps on 1 mount point.It is not about the maximum number of listeners as a limiting factor but the overall bandwidth icecast (we are using 2.4.4) is able to utilize. We can let more listeners to connect only by decreasing the outgoing bitrate that is going against quality.We have looked at icecast web stations globally and what we have found is that NON of them are exceeding the 1 gbps limit. Like servers having maximum number of listeners (18000) but using only 48 kbps bitrate which is around 900 mbps...Please advice! Is this really the limit that one icecast server can utilize/mountpoint?Please link a server that goes over the 1 gbps limit continuously...Thank you for your help!Best Regards,Zsolt Makkai
