I will give confbridge a try, should be a good start to gather some data. I see there is already resampling possibility in confbench.c, how would I add some audiocodecs encoding / decoding to that to get a more realistic example? Cheers, Thomas, who is really interested what the outcome of such a test will be ;) 2008/5/28, Benny Prijono <bennylp at pjsip.org>: > > On Wed, May 28, 2008 at 11:19 AM, Thomas Plotkowiak <plotti at gmx.net> > wrote: > > Since it is almost impossible to find any data on the internet about the > > scaling of conference bridges I would like to do a test myself with > pjsip. > > > > We have confbench.c in samples directory, does it not do what you want? > > > When i talk about scaling i mean the CPU usage for mixing audiosignals. > > A chart like Usage of CPU vs. Number of mixed Audiosignals would be > perfect. > > Another option could be CPU vs. Number of decoded Audiosignals (or > encoded) > > > > My Problem is: In terms of bandwith a 100Mbit Server would theoretically > > capable of recieving around 6000 16 kbit Streams before he runs out of > > Bandwidth, but i think that it rather runs out of CPU instead with > already > > 500 Streams to be mixed in the conference bridge.
