I know NR is async' but this is weird.

I am starting to build my flow for my new project.

I am writing it in blocks so as to help keep things understandable.

I am using `link` nodes to represent inputs from buttons. As the code will be written else where it seems practical doing it this way.

So the _problem_:  
I press an `inject` node to simulate a button being pressed.  
The flow is split. One goes to a `link` node and the other goes to a `change` node.  
The `link` goes to another `link` higher on the screen, and then also goes into a `change` node. That sets `msg.payload` to `CLS` and that is _Send to display_.  
Back to the second branch: that goes to a `change` node which loads an object into the payload and that is .... _send to the display_.

This machine is a Nuc with memory and CPU to spare.  
I am not getting why there is such a lag with the messages getting through.

The _red_ is the first part. The _blue_ is the second part. The blue message arrives at `16`. The red message at `27`. That's **eleven** seconds! and it is doing less than the blue message.

Add named debug nodes at each intermediate point and see what the times are, then you will know where the delay is.
