How can bootstrap time be measured?

General

What is the average system bootstrap time for node-red application? How can this be measured?

Do you mean from a cold-start to flows running? If so, the log will give you that information directly:

But I'm not sure there is a meaningful "average" since it is highly dependent on your platform, resources, how many nodes are installed and how complex and of what type your flows are.

BTW, the above is my dev PC output where I'd just installed the latest Node-RED beta. My live server would give different results of course.

Of course if you run a complex setup on a Pi Zero then it will take much, much longer.
