Time after time, people always ask "How do I calculate how much horsepower I need for FreeSWITCH".

It was a load test with sipp... The scenario was sipp generated calls into freeswitch with its media reflector turned off, freeswitch answered the calls and played back a static audio file... Call duration was 30 seconds at which time the calls were hung up, sipp was set to originate 1000 calls/sec... Now, that being said only a moron would put 30K concurrent calls on a single x86(_64) server imho... If that server were to be down its costing $18,000/hour (assuming revenue of $0.01/minute). And you know Murphy's Law dictates you would probably be down a few hours a month... Its just smarter (and probably cheaper) to deploy 15 to 20 boxes and have a single node failure not affect over all max call handling capacity On 7/10/13 7:20 PM, "Vincent Xia" <gmangudai@gmail.com> wrote: 30000? that's incrediable, is FS able to handle that amount of threads in a single process? what about the call loss rate while running 30k concurrent calls? 2013/7/11 Ken Rice <krice@freeswitch.org> You're going to have to load test it in your specific configuration and go from there... Things like number of calls that have to get transcoded, amount of call recording, etc etc will greatly affect the number of calls you are going to get... Unfortunately there is no general rule of thumb, however, I can tell you to scale that large you are going to need a number of servers not just one large one... You're talking 60 to 80,000 call legs there. The most single leg calls I have ever seen on a box is 30K, and then it was just playing back a media file, and it was a very large box...
