Hi team, good afternoon, I wanted to ask about the minimum software and hardware requirements recommended for developing flows in the Node-RED editor.
We're currently encountering performance issues -specifically script delays ("This page isn't responding" pop up window) - while attempting to merge large flows (around 15 MB in size). This is occurring in our environment running Node-RED 4.0.9 with Node.js 20, on a Windows 11 system equipped with 16 GB of RAM, a 10th Gen Intel Core i5 processor, and the latest version of Microsoft Edge (with only one tab open).
Any guidance or insights you can share would be much appreciated.
Thanks and Regards
15MB of flows is impressive. If you are using subflows too, then that likely expands even further (think of each subflow instance being a duplicate of the subflow template)
It might be time to scale out with multiple instances of Node-RED.
I typically break my flows up into domain specific or logical sections and have them communicate to/from each other.
If you are unfamiliar with this or want a robust way of managing multiple instances, you might want to look into FlowFuse - you can host your node-red instances in the cloud offering or on premise. FlowFuse is open source too if you want to give it a go?

Thanks Steve, I'll read the docs and try it out.
Anyway, do you have let's say minimum requirements that you can share with me? If not, feel free to close this topic.
Regards
