[Icecast] Unable to utilize past 1 gbps

[zsolt makkai]

Dear Icecast,

We are operating a web radio on a 10 Gbps dedicated server line. 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
