Hi,

I am developing a software to manage flow on items, and i have some trouble with performance and parallel process.

Subject:

• The flow is very simple, it will check date and some parameters and use boolean check to decide what is the next step. I have only 5 tasks in my flow.

Technologies:

• Java SE 6
• Spring v4 + hibernate + Atomikos XA
• DB2 database v10 + MQ
• JBPM v6.3

What i want to do:

• All items are independent. So i would like to start n Threads on the same instance and launch parallel process at the same time.

How:

• I am using scope="prototype" on each beans that is part of independent thread. My runtime manager is configured with "PER_PROCESS_INSTANCE".
• All independent threads get item to process, and launch a process.

My problems:

• I can see with logs that all threads want to launch process in parallel. But there is only one process started at the same time.
• I have another problem with the method complete work item. This took more than 100ms and i doesn't understand why.

Thank you in advance for your help or hints.
