Icecast Streaming Media Server

[Benicio]

I did looked through the section of Icecast Load Test Results (by oddsock)
And understand that for the maximum number of listeners - the limitation is bandwidth.
In HW it's just the case if there are too many source clients so we need also keep in mind that each source client adds about 672KB to the virtual size of the icecast proces (but it's looks like not the real case).
So I want to ask about the situation:
For example i use 100Mbit bandwidth from the server. Assume that network utilization is near the 100 Mbit/s, what would be with the server (icecast process) if another one listener ask for the stream???
The service will not run for him?
Or will he gather the stream, but it will be the case of degradation in all other streams?
Or maybe this issues is networking, not in configuring of icecast?

For the main code each source will add a fair bit because of stacks although normally not much of that is actually used but does ad d a fair bit to the VM space if you have a lot of streams, the kh tree reduces that considerably now.

If you are near max bandwidth then icecast won't know unless you give it a limit to work to, eg max-listeners. If the new listener is within the limits then they will be allowed on but if max badnwidth is reached then the stream bandwidth will be throttled at the OS and so listeners can fall behind and drop off the queue. There is no prioritising of listeners currently.
