As a side note, would be great to have a official recommended language for KEMI so other devs can share modules/codes/tutorials etc.. having too many languages, in my opinion, reduces the benefit a community can provide.</div>

<b>Subject:</b> [SR-Users] Performance tests of native vs. kemi scripting for SIP routing</font>
<div> </div>

<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">Hello,<br>
<br>
during the preparations of Kamailio v5.2.0 and the days after, I got the<br>
time to run some tests in order to see the differences of running<br>
similar SIP routing logic when using native configuration file scripting<br>
versus KEMI languages. So far I did it for Lua and Python (v2),<br>
hopefully I will find time to run also for the rest of supported<br>
scripting languages: Python (v3), JavaScript, Ruby, Squrrel and Lua with<br>
LuaJIT.<br>
<br>
The pleasant surprise was to see that this time, the results of using<br>
Python were similar to native scripting and Lua. When I did some basic<br>
tests during development of KEMI, using Python seemed slower.<br>
<br>
More details about how tests were performed, the config files/scripts,<br>
used tools and results were published in a wiki page:<br>

<br>
Should anyhow of you have some time to run the tests in own environment<br>
and share the results (on sr-users mailing list), it would be<br>
appreciated and would help to validate the tests and discover if I<br>
forgot something in any of the configs. Note that the goal of the tests<br>
is not measuring the capacity of Kamailio in your environment, but see<br>
the differences between using different scripting languages in the same<br>
environment (so you can do the tests on raspberry pi, if you like).<br>
<br>
I would also be interested in knowing if you are using Kamailio with<br>
KEMI or you are planning to, if yes, which scripting language. If<br>
already doing it, is already in production? These are useful to plan<br>
where to allocate developer resources in the future...<br>
<br>
And to start, I am running Kamailio with Lua (4 instances) and Python<br>
(1) scripting in production deployments, with very good results so far.<br>
<br>
Cheers,<br>
Daniel<br>
