Hi all, I build a new test boxes for freeswitch. and trying to simulate high load condition. I have one freeswitch box that host conference apps, and another box with simple js to originate call to the conference room. To monitor the sound quality, I have one phones that dial into the conference room, and then start streaming/playing moh music in the conference. In many scenario that i tried (mute, unmute, one or multiple rooms), the max total number of channels is about 170 channels before FS start to slowing down on creating new channels. The Cpu's only tops around 40-50%, and the voice/rtp start to jitter or delays on my phone. These test boxes is running on 2 processor 2.8GHz Dual Core xeon cpu's and about 1Gb memory. I think the number already pretty impressive, at least for me :) But is this limit sounds right from others experience? Can I still do more tuning? Thanks, Johny K.
