Hi folks,

I have somewhere a bottleneck in a chain of nodes. So I would like to inject a message in that chain of nodes, and measure the _ **process timing** _ of that message in each node of that chain. I.e. how long it takes for every node to process that message. I don't want to get overwhelmed by other timing information from other nodes in my flow:

Was wondering what is the best way to do that: via metrics, via the flow debugger perhaps, ...

Thanks !!  
Bart

Perhaps not the best way, but a reasonable (and simple) way is to use this...

Thanks for the pointer!  
I had hoped that perhaps someone meanwhile had build some kind of time profiler based on the message hooks 😉

Thanks for providing this, @Steve-Mcl ! I've been curious about processing time in a couple of my flows but hadn't gotten around to finding a way to show it.

Would something like [node-red-contrib-msg-speed (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-msg-speed) help you?

Hey @Bobo,  
Not exactly, since I developed that node to measure the speed of messages. I.e. how many messages pass per time unit. But now I want to determine which node in a chain of nodes is the bottleneck.  
The subflow from @Steve-Mcl will do the job.
