Hi,

I am currently working on a sample application using a single jBPM5 BPMN Process and using persistence in a *postgresql database*.
I want to test *remotly* my process from two ways :
1. in a classical way that is to say :* drop my BPMN file into the sample\evaluation\src\main\resources
* include my business classes in a jar included in  jbpm-gwt-console-server.war\WEB-INF\lib
* "invoke" my process through the REST API coming with jBPM 5.3.0

2. in a web application which embeds jBPM runtime and test it by exposing some REST services

I want to test the load of the jBPM5 Engine by sending "some" REST requests to simulate a lot of users interacting with my process. Of course I also want to send many parallel requests to see how the jBPM5 engine reacts from a concurrency point of view.
My future application may have this kind of requirements.

So my question is :

What are the advices that the jBPM team can give me to configure in an appropriate manner JAS 7 / Persistence / ...  so that performance could be the best as possible.

* One parameter I see is increasing the max pool size of the postgresql datasource in standalone.xml
                        <max-pool-size>
                            yy
                        </max-pool-size>
* Are there any others parameters on which one can play with or things / tips to know to encounter the least performance issues?

Thanks for help and replies coming  ;) 

Kind Regards
