<div dir="ltr">Dear Marius,<div><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">http://45.67.158.93:8000/status.xsl</a> For the slave: <a href="http://45.67.158.94:8000/status.xsl">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><br></div><div>Thank you for your help!</div><div><br></div><div>Best,</div><div><br></div><div>Zsolt</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Marius Flage <<a href="mailto:marius@flage.org">marius@flage.org</a>> ezt írta (időpont: 2024. márc. 14., Cs, 23:01):<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><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?

Speedtest?</div><div dir="auto"><br></div><div dir="auto">Maybe consider scaling with additional Icecast servers and use a load balancer in front? And then just scale accordingly?
