Hello Anton<br><br>If you are designing simple stuff with python , stick with it.<br>If you are using tons and tons of IVR's calls , Lua is more lightweight , don't forget that python is a highly heavy duty language.<br>
<br>If you process a large number of ivrs ( millions) ESL will be the best solution you can find a server.py in your pythonesl folder , if you can't find it drop me an e-mail.<br><br>Currently i'm developing a framework that will behind a load Balancer scale the "Application" part of the ivr's.<br>
<br>A smal framework for your case could be :<br><br>server.py from pythonesl > It's A threaded Server Not MP , means every call will be equal to 1 thread ! Be carefull :D<br>Sqlalchemy will support connection polling.<br>
<br>If you need further help just ask :)<br><br>A/T<br><br><br><br><div class="gmail_quote">2011/4/27 Nicolas Brenner <span dir="ltr"><<a href="mailto:nico@clickfono.com">nico@clickfono.com</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
After having used Javascript and Lua for scripting in FreeSWITCH, I would recommend using ESL for anything serious. There are many advantages to using ESL instead of a script inside FreeSWITCH, but the main one for me was easier call control, especially when doing asynchronous stuff. I believe there's a Python version of the ESL library, so you shouldn't have much trouble getting started.<div>

Hello!<br>
Cannot get answer for myself for languages processing overhead/preference,<br>
<br>
I personally would like to use Python for scripting under Freeswitch,<br>
but considering some recent list activity about low CPS while using<br>
python scripts, etc<br>
querstioning, maybe it's better to use LUA instead? WIKI or list does<br>
not answer this questions in satisfying manner unfortunatelly. For DB<br>
intensive scripts - DB connections pool is a very important stuff,<br>
having direct influence performance and CPS specifically.<br>
<br>
It looks that lua might be lighter and more tightly integrated to FS,<br>
but if processing overhead difference is just a few times python is<br>
still preferred for me (and many others) since much more<br>
powerfull/libraryreach/etc.<br>
I'ts would be just nice to clear this question.<br>
<br>
1. Is there any comparisions on plain processing overhead?<br>
2. Any data on memory consumtption per active python process?<br>
2. Is there a freeswitch DB pool connection interface like for LUA in<br>
mod_python?<br>
3. If not - what would be the known technique to use external DB<br>
connection pool from inside the FS python script?<br>
4. Seems logical, but please confirm/reject - once executed (compiled<br>
to the bytecode) - the second time the python script under FS will be<br>
executed as precompiled bytecode?<br>
<br>
Regards,<br>
Anton.<br>
