I tested both MySQL and PostgreSQL under various loads, Actually got paid to do it. In the simple case where one process just stuffs data into the database with INSERT MySQL was about 4x faster in terms of INSERT/second
However if you have five or six processes that are doing lots of transactions, mixed INSERT and SELECT, MySQL grinds to a halt The trouble is locking. MySQL only lets one process at a table at a time so everyone else is shut out waiting.
On a large PBX with high call volume you can't afford to have a table locked for 10 or 30 seconds while some guy does an ad-hoc join.
PostgreSQL is more stable but can "only" do a few hundred INSERT per second on PC hardware vs. well over 1000/sec for MySQL.

I agree. postgres could be too slow if used into a big system and you can't afford a rather good machine.
mysql is very fast and simple.
and I don't see where's the problem into the extraction...
a simple division could be done in any language, with any
program...

I have noticed that the duration times for all calls are recorded
in
seconds, by Asterisk. Is there a way to set the recorded call
duration
to a decimal representation of minutes? ie 90 sec = 1.5 min. My extraction process would be a little simpler if the data dumped
into the
database were minutes and not seconds.
Write a trigger for on insert or a view that converts sec->min.
Oh wait
your using MySQL. Use PostgreSQL ;)
