So have you tried writing with the smaller mod_json or even smaller mod_cdr_csv with your own small template?

Or having mod_xml_cdr / mod_json_cdr POST the CDRs to another machine to process?

Yeah, I believe so, since when calls are establishing the cpu load is not a problem.

From my experience playing with different CPS values. The CPU spike is usually caused by the 'tearing down' process. If you increase the call duration, you will be able to see CPU spikes when channels times out and starting to tear down.

Hi all,

I searched for FreeSwitch call capacity, but most of the results wasn't new. So, I wanna ask if anybody has either tested FreeSwitch's performance recently, or got a dramatic result in real environment?

I tested call quality on this machine:

Virtual FreeSwitch server
OS: CentOS release 6.2 - x86_64
CPU: 8 processor - Intel(R) Xeon(R) CPU X5670  @ 2.93GHz
Memory: 8 G

After receiving incoming calls, FreeSwitch routed them to another sip server, without transcoding. The other server transmitted calls by playing an audio file.  Meanwhile, I called an extension in FreeSwitch to test the call quality.

The result was like this:

1000 Concurrent calls
Call duration: 160s
Call rate: 6 cps (just creating channels)
Max used Memory: 1416M
Max CPU load: 0.24
Max Network throughput (recv/send): 6711k/80k
Quality: Good

This test was taken before tearing down the channels.

Then, I took another test to estimate calls per second, and it wasn't what I was expected!


150 Concurrent calls
Call duration: 4s
Call rate: 30 cps (creating and tearing down)
Max used Memory: 1293M
Max CPU load: 4.50
Max Network throughput (recv/send): 828k/60k
Quality: Average

And when I increase call rate to 50 cps:

1000 Concurrent calls
Call duration: 4s
Call rate: 50 cps (creating and tearing down)
Max used Memory: 1730M
Max CPU load: 29.9
Max Network throughput (recv/send): 1367k/202k
Quality: Bad

Why call per second is such a big problem? Did anyone get a better result on this?

Thanks,
Hanie
