Create Multiple Workflowinstance

Hello,

 
Is it possible to create more the one Workflowinstance of a WorkflowDefinition at e.g. one btnClick?
And can I start all those Workflowinstances at e.g. one btnClick?
 
Try to Create about 500 pieces by using a For loop.
But application start to Hang.
I'm interessted to know if this is possible and how to do this properly.
Can anybody please give an answer to this question?

There is a chapter in manual named "Running an instance from code: full example", have you checked that? Is there any specific question or problem you got from that code?

Thank you I'll try that.
