    <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>
    </p>

            <div><br>
            </div>
            <div>We have tested extensively the bandwith with speedtest.
              We tried with iperf but that did not finish for a long

            <div><br>
            </div>
            <div>Currently we are load balancing on two 10 gbps

              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>That was our second idea that somewhere in the

                  </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>
