Hi everyone!  
Can you take my answer.  
Example:  
I'm reading 500 devises from ModbusTCP protocol. Only 10 registers from each devise. Does it is working, in one or more flows. And visualisation in to Node-Red Dashboard.  
Will the node-red server have enough resources to process this amount of information? And how you can calculate the performance of the system when planning a project. Please share your options.

You need to tell us how often you are getting values and what kind of server you are using.
