IMHO, it is definitely NOT EASY to come up with a standardized test without some standardized network configurations and standardized load generation tools. It is even harder when a non-standard or niche application use is intended. For example: I had to run a bench mark with live traffic calls that entered by the PSTN and VoIP gateways into a PAY-FOR-PLAY farm of asterisks. I had to generate a minimum load of 5,000 simultaneous calls with a specific distribution of call durations and to continuously pump that traffic to attain specific objectives for rate-of-arrival on new calls. This required me to tie up 10,000 phone lines. 5,000 outgoing calls to specific numbers that would be terminated by specific carriers plus another 5,000 inbound VoIP and TDM lines to receive those calls. Reason eventually prevailed and we got the marketing & program managers to understand what can be shown by a much smaller set of lines (3,000 total, 1,500 IN and 1,500 OUT). This was a 3% sample of the intended full scale loading rather than a 10% loading. I would not expect any generalized benchmark to even begin to address all of the non-Asterisk elements in this over-all system. Indeed, how could I even base any estimates for this based on generalized benchmarks for products optimized for mass-market PBX,IVR, or CALL-routing applications. I am using extreme examples to make the point that the Integrator-Reseller has that responsibility. For the non-extreme examples, the vendors conservative estimates for middle-of-the-road users of pre-prepared solutions are just fine. BTW: It required only two guys and one hour to setup and perform the test with Asterisks. It took several days of advanced negotiation to agree on the methodology with all concerned. This is a typical situation when you want to make sure the client knows enough to make a valid decision. ..mike.. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
