What CDR mod are you using? Are you writing large CDRs, e.g. xml_cdr to disk? Perhaps that's messing with the load average. And regarding ACD... for example, my calling card "good" traffic has an ACD of about or over ~3 minutes. See if 50cps but 120-180 second ACD still has that issue... after you check the CDRs. -Avi On Sat, Jul 7, 2012 at 8:55 PM, Henry Huang <red.rain.seven@gmail.com>wrote:
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
