[Icecast] Unable to utilize past 1 gbps

[zsolt makkai]

Dear Marius,

In addition to that attached please find a screenshot from Proxmox on
statistics.

Do you know any ice cast servers that puts out more than 1 gbps for a
longer period? Just curious whether anyone was able to go beyond 1 gbps for
an extensive time.

Thank you!

Best,

Zsolt

>> 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!
