Feature request: Node performance analyzer

I have over 200 nodes installed and the comflicts are starting to kill my rendering time on edge/chrome/ff.
I tried using the performance tab in the dev tools but it's all returning 'comfy' rather than the names of the indivual nodes having an impact.

I think it would be great to have access to 'how much impact' each node set has on load times, especially as it's pretty wild what some of them are doing to the DOM right now. Maybe it could piggy back on some browser internal analytics to tell the user that node xyz is seriously impacting performance.

Long shot i know but this would be a great QOL improvement.

Thank you!
