Is there any tooling available to help me visualise/understand the resource dependencies, resource provisioning time, and actual vs max parallelisation of a

pulumi up

? I'm looking to understand if there's potential improvements that could be made anywhere through the whole stack.

I'm not aware of any. Try turning on the verbose logging and seeing if there's something in there that you can parse out and build timings from?

Totally. I'll look into how to do this. Any idea on what flags to get access to those timestamps/data? (or links to docs) Haven't dug too deeply into pulumi logging options.

I think

--logtostderr -v=9

should give you almost everything? There are higher levels of debug output, but 9 is pretty ott, should capture everything you need.
