Resources consuming Node-Red

Good morning to all readers of this query, I put them in context, I use S7 nodes very often, Modbus to be able to read PLC variables or other devices that support these protocols, but my query is how many variables can I have at most? reading at the same time, because I don't think the number of variables is infinite, and I think this will depend on the characteristics (ram, storage) of the device hosting the red node.

So how do I know if my hardware features can support all the variables read by node red, or how do I know how much ram or how much space my node red application consumes?

I hope I have made myself understood, thanks in advance.

This is pretty much a "how long is a piece of string" question.

Maybe you should start with how many registers and how many external PLCs/devices do you need to access. Then we can tell you of the pitfalls and gotchas to look out for.
