Re: [Freeswitch-users] Estimating Call Capacity
Although, FYI, I just benchmarked mod_xml_curl on a separate web app server from FS with FS on a Dell R710 with their current best processor option (Intel Xeon X5570 @2.93GHz with 8-cores total) and 32 GB memory. The web app server is less than half the power of the R710. I maxed the web app server at 300 calls per second (both setting up and tearing down) and the R710 running FS was 65% idle. No audio was being proxied through FS, though. If I were running the web app server on an equivalent R710, they probably would have been on-par with each other in performance. Extrapolating, I expect that in such a case I should be able to get at least 650 CPS out of FS, though for production I would probably limit it to 400 CPS or less so I leave room for miscellaneous tasks. I maxed out the R710 at over 16,000 simultaneous calls (again, no audio proxying) but the only reason I couldn't do more was because I hit some sort of thread creation limit in Linux. There was about 17 GB of memory used for this many calls. This should give you some ballpark idea of what you can accomplish with FS. At some point, I will track down and resolve the thread creation issue, at which time I believe call limits will be limited either by a complex combination of available memory, the speed of the processor, the cost of thread context switching, calls per second setup rate, and call duration. -- Eliot Gable

A little off-topic, but since call-capacity is the subject, what are people using to analyze their CDR's to discover this? I'm handling about 30k calls per day but have only a bandwidth-based guesstimate of the peak number of concurrent calls I'm handling. If there's an open source solution, I'd appreciate a pointer.

I'm fond of Vqmanager from ManagEngine. It is a passive SIP monitor. I.E. you mirror the ports that your FS or Asterisk boxes, and VQmanager sniffs the mirrors, tracking all sorts of good data. You can install it on a Centos box, and get a free trial. http://www.manageengine.com/products/vqmanager/index.html What is really cool is that it actually monitors the RTP/RTCP as well as all of the SIP headers and archives the calls, so you can look at calls from several days ago and see EXACTLY what happened on them. I have used this extensively to pinpoint bad Level 3 and X/O media gateways.. Much better than trying to sniff packets in real-time and MAYBE catch a problem.. I've also used it to find/fix several SIP issues w/ odd endpoints.. Very easy to see..

everyone's numbers will jive with your use case. Which is the reason
the project never posts or endorses a set call count.

Hi Shelby, Thanks! That's pretty useful. I also note that this same info is available from the CLI, although I was curious as to what some of the numbers indicated: UP 0 years, 13 days, 19 hours, 25 minutes, 48 seconds, 887 milliseconds, 975 microseconds 529509 session(s) since startup 26 session(s) 0/30 1000 session(s) max Specifically, 26 sessions 0/30... I take it this means there are 26 current sessions, but I'm unsure of what the "0/30" means. Cliff On Tue, 2009-10-27 at 15:19 -0500, Shelby Ramsey wrote:
Cliff,
Try using xml_rpc ... status or show channels will give you what you need.

A little off-topic, but since call-capacity is the subject, what are people using to analyze their CDR's to discover this? I'm handling about 30k calls per day but have only a bandwidth-based guesstimate of the peak number of concurrent calls I'm handling.
If there's an open source solution, I'd appreciate a pointer.
Regards, Cliff

Although, FYI, I just benchmarked mod_xml_curl on a separate web app server from FS with FS on a Dell R710 with their current best processor option (Intel Xeon X5570 @2.93GHz with 8-cores total) and 32 GB memory. The web app server is less than half the power of the R710. I maxed the web app server at 300 calls per second (both setting up and tearing down) and the R710 running FS was 65% idle. No audio was being proxied through FS, though. If I were running the web app server on an equivalent R710, they probably would have been on-par with each other in performance. Extrapolating, I expect that in such a case I should be able to get at least 650 CPS out of FS, though for production I would probably limit it to 400 CPS or less so I leave room for miscellaneous tasks. I maxed out the R710 at over 16,000 simultaneous calls (again, no audio proxying) but the only reason I couldn't do more was because I hit some sort of thread creation limit in Linux. There was about 17 GB of memory used for this many calls. This should give you some ballpark idea of what you can accomplish with FS.
At some point, I will track down and resolve the thread creation issue, at which time I believe call limits will be limited either by a complex combination of available memory, the speed of the processor, the cost of thread context switching, calls per second setup rate, and call duration.

Here are a few benchmarks that I had stumbled upon.

Please remember NO benchmarks are endorsed by the FS community or
developers, because there are just too many variables, and a simple
figure is just useful for marketing hype, not for real dimensioning.
You MUST do your own benchmarking, so you get an idea about how to
dimension for your own use case and hardware.
Thanks,
Vinuth.
