[Freeswitch-users] Performance Testing

The common answer is "it depends"..

It depends on many different aspects, for instance: transcoding, script handling, media bypass etc. So there is no answer that is valid for everyone. There are also easy changes that can be made to improve performance, putting the sqlite databases on a RAM-drive is one common task.

Also make sure to have as many CPU cores as possible, lots of RAM, and med sure to use 64-bit systems.

I've never done any testing myself, so I don't know really. But I know there are people out there handling thousands of concurrent calls, at pretty high CPS.

One more thing though, that will help you out right now. FS doesn't behave 100% correctly in CentOS 6.x, CentOS 6.x causes much higher CPU load, compared to CentOX 5.x. So right now CentOS 6.x is not officially supported by FS (until the reasons for this has been discovered). If you switch to real hardware and use CentOS 5.x I'm pretty sure that will give you much better results.

These issues on Jira are related to CentOS 6.x problems.

Thanks Peter, I will definitely test with a real server too. But, first of all, I'm really interested to know that what the result looks like for the others (perhaps with real servers in real environment).

Before trying anything else, use real hardware instead of virtual. A virtual server with this kind of load will only cause you trouble. Actually - most virtual solutions will cause you problems :)

Also, performance with average call duration of 4s is not really anything that would happen in real life.

But first of all - get real hardware.

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?
