<p>Hello,</p>
<p>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.</p>
<p>Because Lua 'exit' cannot be used, KSR.x.exit() is a workaround
relying on error/exception handling with string comparison that I
did.</p>
<p>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:</p>

<div>Hi Daniel,</div>
<div><br>
</div>
<div>For lua example, it's just an error when writing my
email... in my config file I have KSR.x.exit();</div>
<div>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.</div>
<div>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.</div>
<div>Next step, is to use a more complex config file.</div>

<p>Hello,</p>
<p>is it really just 'exit' in the ksr_core_received()?
Because that should shut down kamailio.</p>
<p>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?</p>

<div>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.</div>
