[rules-users] Drools server, memory footprint

[Mauricio Salatino]

Hi Bertrand,
yes.. your scenario sound realistic.
Remember that drools sacrifice memory for performance, in other words if you
create 1 million of objects, the memory footprint will be high because of
that.
There are different ways to distribute the load to different Virtual
Machines and different physical machines. You can see the VSM apis
(experimental) and also the Drools Execution Server that you mention. We are
releasing a new version of the execution server that will make things
easier.

Greetings.
