Node Performance chart

Hi, could anyone share a link to a performance chart documenting the render time cost per node?

It doesn’t exist as far as I know, and given that performance highly depends on the parameters I’m not sure it makes much sense.

I wonder if it made sense, but then I thought yes, it could if each node was broken down further into highest/lowest cost from tested parameter combinations, and all nodes were tested on the same scene by being added to the existing tree accumulatively.

Would be interesting for things like, glossy + refraction VS glass, or lightpath ray depth vs light path shadow ray.
