Announcing Public Preview of Azure Functions Flex Consumption

I have a question......

I was really exited to take part in the preview. But now I have some questions regarding configuration.

I have the same setup in Windows Consumption/ Linux Consumption/ Flex Consumption. (Compiled sources are identical.)

I have a program that does the following:

1. Message is sumitted to a queue
2. Queue Trigger will create Orchestration
3. Orchestration will have 3 to 5 activities
4. Last activioty will write the mesage to a queue (effectively step 2 but then for another orchestration)

Now on Windows this runs Super !

On Linux Slower (a lot) but it runs!

On FlexPlan it is extremely slow!.

The messages get picked up from the queue and then waits 30 seconds to 5 minutes before the activity starts.

It also seems the function immediately shuts itself down after processing  a couple of messages... (So there is another wait for 30 seconds)

Not sure if it's something ion the host.JSON or a configuration of some sort.

Where can i go with questions regarding the flex plan.
