It's slightly more work to tweak it than just editing a script since you'd need to recompile and reload the module, which might also be trickier if you're handling traffic at the time.<div>
<br></div><div>Lua (mod_lua) is probably the most commonly used language, but there's also Python (mod_python) as you've spotted. There's also JavaScript (mod_spidermonkey) which you haven't mentioned. Which you use is really up to you though.</div>

It gives you a database interface without having to install and configure luasql, and you get to take advantage of the FS connection pooling which you wouldn't if you were using the native support. That'll should speed up database access times (you'll in most cases already be connected to the database so the call doesn't have to wait while you connect). I don't think that interface is available in the other languages just yet though.</div>

I know i can't express my desires in the normal XML language, because I need looping and database access, so which language is the best tested and most reliable in terms of usage with FreeSwitch. My finalists so far are Lua, Python, and good old C. Haven't used python or lua yet, but I figure C will have a big performance advantage.<br>
<br>
but maybe not important considering how much greater the CPU load in the switch is devoted to handling audio streams...<br>
