CcBPM - ParForEack block not processed in parallel

Question

Hi Experts,
I am using a par for each block in my integration process.
Within the block I send several synchronous calls to a JDBC adapter to execute stored procedure calls.
The stored procedure calls need to be executed in parallel.
In the process list ( Transaction SWF_XI_SWI1 ) I can see, that all the workitems are creat at the same time.
However they stay in status READY and are getting processed by PE runtime only sequentially.
Any idea, what is the reason of this system behaviour? Are there any workflow setting missing?
thanks
Barbara

Hi,
in case of ParForEach, the workflow log ( view with technical details ), my the node strucure of my block looks like this.
-->Block1
         --> Branch 1
       --> Block1 
        --> <my synchronous send step>
   --> Branch 2
       --> Block1
        --> <my synchronous send step>
   --> Branch 3
       --> Block1
        --> <my synchronous send step>
   --> Branch 4
       --> Block1
        --> <my synchronous send step>
   --> Branch 5
       --> Block1
        --> <my synchronous send step>
   --> Branch 6
       --> Block1
        --> <my synchronous send step>
The nodes printed bold are the nodes, where a workitem is created. So I have 6 different workitems created in my example.
All these workitems have the same creation timestamp. But the nodes below ( send steps ) have different ( ascending)  timestamps, which means, that these nodes are processed sequentially.
In case I change the mode to ForEach, the workflow log looks like this:
-->Block1
--> Block1
--> Loop 1
   --> my synchronous send step
--> Loop 2
--> my synchronous send step
--> Loop 3
--> my synchronous send step
--> Loop 4
--> my synchronous send step
--> Loop 5
--> my synchronous send step
