<p>Hi Zsolt,</p>
<p>looking at the metrics from Proxmox it doesn't look like anything
breaks there. What about at the operating system level? Could
there be some limits there? Have you checked corresponding kernel
or system logs? Which OS/distribution are you using? Checked the
logs there? If nothing screams there, maybe start looking at a
load balancer and scale with several more VMs?<br>

</div>
<div>Our station is Megadanceradio in Hungary. </div>
<div><br>
</div>
<div>Our status page for the master server is: <a href="http://45.67.158.93:8000/status.xsl" target="_blank">http://45.67.158.93:8000/status.xsl</a>
For the slave: <a href="http://45.67.158.94:8000/status.xsl" target="_blank">http://45.67.158.94:8000/status.xsl</a> </div>
<div><br>
</div>
<div>We are peaking at around 11.00 am and 13.00 pm in the
afternoon.</div>
<div><br>
</div>
<div>We have tested extensively the bandwith with speedtest.
We tried with iperf but that did not finish for a long
time so we stopped it. </div>
<div><br>
</div>
<div>Currently we are load balancing on two 10 gbps
dedicated lines. So for now we are ok, but for the future
we do not know for how long it will last. Currently we are
limiting the number of listeners to 5200 on each server so
as not to cripple the system. When we are approaching the
bandwidth limit we are getting loads of timeouts until
finally not being able to access even the status page. </div>
<div><br>
</div>
<div>That was our second idea that somewhere in the
production chain there is a limit set but we did not find
anything.</div>

<div dir="auto">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?</div>
<div dir="auto"><br>

<div dir="auto">Maybe consider scaling with additional
Icecast servers and use a load balancer in front? And

<div>Emne: [Icecast] Unable to utilize past 1 gbps </div>
<div><br>
</div>
</div>
<div dir="ltr">Dear Icecast,
<div><br>
</div>
<div>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.<br>
</div>
<div><br>
</div>
<div>We found that no matter what we do overall upload
cannot go over 1 gbps on 1 mount point.</div>
<div>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. </div>
<div><br>
</div>
<div>We can let more listeners to connect only by
decreasing the outgoing bitrate that is going
against quality.</div>
<div><br>
</div>
<div>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...</div>
<div><br>
</div>
<div>Please advice! </div>
<div><br>
</div>
<div>Is this really the limit that one icecast server
can utilize/mountpoint?</div>
<div><br>
</div>
<div>Please link a server that goes over the 1 gbps
limit continuously...</div>
<div><br>
</div>
<div>Thank you for your help!</div>
<div><br>
</div>
<div>Best Regards,</div>
<div><br>
