Good to know about performance improvements in WF 4.0

I am creating one workflow instance for each of my order in an order management system. So the number of workflow instances will be around 100000 of a single workflow.

Need to know as what is a decent limits of workflow instances which can be created on a server.While suggesting, also share your server configuration. I am thinking of about 100000 workflow instances hosted as a service in IIS.

These workflow instances will work and die out with persistance only incase of system failure.

--------------------------------------------------------

Do you have performance figures on how many instances of workflow can be created at a time when the workflow is hosted as a service in IIS using AppFabric.

Also if you could share data about how much time it is going to take for a workflow based on wf4 to exceute which has one policy activity with externalised 10000 rules.

Please share whatever performance data you can share along with configuration of the server for which the data is relevant.

Future of WF article - I think that WF has a glowing future. Create an admin tool that defines work processes for computerized and digitized processes. I call this eStrategitizing (can this be a word?). Think - you will be able to draw your job with a drawing tool like Visio!
