The OP mentioned that the load is around 10% at 330cps, so load is not an
issue. Traffic bottleneck can be an issue.
The default udp queue length is not enough for high cps.
And of course, you need to keep a balance between all the variables that
affect traffic :)

Thanks Alex!
I already knew that article, and followed it. But it doesn't seem to have
had any positive impact

UAC and UAS are both SIPP instances, in separate VMs.
On Kamailio server, I use the "ss" command instead of the one you suggested
(using watch -n 2 ) , and only from time to time, like every minute or a
bit less, and for 1 or 2 seconds, there is some changes on the field you
mention, with values be
Sergio,
You may consider giving this a read:

Child processes will make a big difference, especially in your scenario #1,
where you're waiting on outside services.
But it's possible you've just run int
Totally agree with Alex here.

I don't know that I would do that. If your server isn't coping with the load,
making the kernel receive queue deeper doesn't increase throughput, it just
relocates the queueing -- or rather, adds another layer of queueing.
Squeeze the balloon in one place, it inflates in another.

I'm really not sure what to tell you, Vishal. The documentation isn't entirely
clear for all use-cases, but it literally lays out exactly how to do this. You
just have to read it.

Take a look at documentation module:
https://www.kamailio.org/docs/modules/5.8.x/modules/rtpengine.html#rtpengine.p.rtpengine_sock
you can define more RTPEngine Servers with or without weight for balancing
You can use rtpengine table too:

Have you checked the docs for rtpengine? AFAIK it is documented quite well
there.

Hello Everyone.
I am looking for documentation to have multiple RTP Engine servers
connected with kamailio using db url and balance the load accordingly.
Thanks

What do you have as a UAS?
The UDP receive buffer increase that Ovidiu suggested would be necessary if
you see traffic piling up/getting dropped, e.g. look at `netstat -s | grep
"receive buffer errors"` or watch for 2nd column Recv-Q of netstat.

I assume that you are using udp.
Please increase the length of the udp queue:

Hi all!
I have been doing some performance tests with Kamailio 5.7.4 and SIPp.
The infrastructure is as follows:3 VMs running on VMWare ESXi running:
UAC on 10.20.0.1 with SIPP-> Kamailio on 10.20.0.5 -> UAS on 10.20.0.3
The Kamailio VM has 6 dedicated vCPU of type Intel(R) Xeon(R) Silver 4216

Hi,
i've the same problem on Kamailio 5.5.7, how do you resolved it?
Best regards.
