-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, ~ I have just installed Ice cast and I really like it. I want to stream a radio station which expects 6000 concurrent listener. I was thinking of using an SMP machine with Linux running.

It does use threading internally, but not to an extensive level. The real problem with 6000 concurrent listeners is the bandwidth. At 128 kbps, that's 768 Mbps, which is more than almost any host can sustain. The usual method here is to set up a handfull of servers in a round-robin, and have each relay from a master icecast instance. Hope that helps, -r

A sort of stress-test, which would make the server act exactly the same as if it was in real conditions... I tried running many ogg123 / mpg123 in null output, but it overloads the client machine too fastly... -- Cl?ment Cavadore www.frequence3.org Webradio Francophone

Just try wget -O /dev/null -q http://YOURSERVER:8000/YOURMOUNT & and start as many of these as you want. You can stop them with killall wget afterfards. Wget makes an ordinary http download (exactly what mpg123 / ogg123 is doing as well) but doesn't decode the media. The data are put to /dev/null. Enrico

I've not tested it to above 3000 users, but that was on a 400 MHz single processor machine. Icecast will make use of SMP (it's internally fairly heavily threaded). Mike
