Hello,
can you remove the KSR.x.exit() and test again? It will be the same
effect from sip routing point of view, just to see what is the result.
Because Lua 'exit' cannot be used, KSR.x.exit() is a workaround relying
on error/exception handling with string comparison that I did.
However, overall KSR.x.exit() alone has an insignificant effect on a
production configuration, based on the tests I did for kamailio 5.2, you
can look for more at:

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 !
