Hi,
I am performing SIP to SIP performance testing using Kamailio proxy
(UAC-Kamailio-UAC). After increasing the load to 300 calls/sec
Kamailio begins dropping UDP packets. (250 cps works fine). CPU
utilization and network bandwidth looks fine. I think the bottleneck
is the Linux UDP buffer size of the proxy server. Here is the proxy
server information:
kamailio autodetects and sets the buffer size to the maximum
allowed.
What are the number of children you have in config? Do you get any error
messages in the syslog?
Cheers,
Daniel
$ uname -a
Linux lab-linux01 2.6.24-19-server #1 SMP Wed Jun 18 14:44:47 UTC 2008
x86_64 GNU/Linux
$ sudo sysctl -a | grep net.core.rmem_max
net.core.rmem_max = 131071
The question is if I increase the linux UDP buffer size do I need to
change any configuartion parameter (like MAX_RECV_BUFFER_SIZE) in
Kamailio?
Thanks,
Alex R
