Hi Daniel,

For lua example, it's just an error when writing my email... in my config file I have KSR.x.exit();

I have not tested a more complex config, but I'm curious about kemi framework and how it works. So before anything else I made a simple test to know the cpu overhead.

For this test, I noticed that the Recv-Q of kamailio remains high with kemi/lua, and with the native one remains to 0, with children=1 of course.

Next step, is to use a more complex config file.

Hello,

is it really just 'exit' in the ksr_core_received()? Because that should shut down kamailio.

Anyhow, practically with the examples here, you test the difference between looking up a function and doing exit in native kamailio.cfg and lua script, which is really marginal comparing with the rest of configuration file in a usual production deployment. Have you tested with a more complex set of actions/functions?

Cheers,
Daniel

Hi!

I just made a simple test performance between native script and kemi/lua with the event_route[core:msg-received] callback.

# lua script children=1 cpu.process=100%

function ksr_core_received()

exit;

end

# native script children=1 cpu.process=70%

event_route[core:msg-received] {

exit;

}

# tested with udp 5060, 1000 Mbits/sec

iperf -c 127.0.0.1 -p 5060 -u -b1000m

I don't know if it's normal and what we should expect from kemi, but I would like to share this with you. Maybe someone could confirm the performance difference.

Have a good day !
