Hello,

my current node-red instance has:

- 9 flows
- 6073 nodes
- 112 groups
- 98 configuration node
- 120 subflows

The startup time of docker container is 10min. Is there a correlation between the startup time and number of nodes/flows/subflows? With every new sublfow, the time is increasing.

Sometimes the deployment time (dependent which flow/subflow was changed) is over 2min by small changes.

Are there some limits regarding the number of nodes/flows/subflows?

Node-RED version:to 3.0.2  
Node version: 16.20.1

Thanks in advance!

Best regards!

Of course more nodes will make things slower to load and edit.

You didn't say what kind of deploy you were doing. If you are doing a full deploy then all of your nodes are destroyed and recreated every time, even if you edit just one single thing.

Have a look at this thread. I've linked you to the comment I made about subflows and how there are far more things happening than you might realise.

> and this gets worse if your subflows nest subflows. each instance creates all its internal nodes and if any of those are subflow instances, they are created too. It really doesnt take much to get to huge numbers Example: Subflow1: 10 regular nodes, 5 Subflow2 nodes Subflow2: 20 regular nodes Main flows: use 100 Subflow1s and 100 regular nodes this means 100 + (100 \* (10 + (5 \* 20))) == 11100 nodes to be created, setup, initialised etc etc. Contrast that with link-calls (aka pure funct…

Hi, thanks for the fast reply. Regarding the deployment, I'm using the "Modified Nodes" kind of deploy.  
I will read your thread. Thanks again!
