OP here. This is my attempt to document this profiler in Go based on my own research. As far as I can tell there is not much information about it out there.<p>Happy to answer any questions.
I'm continually impressed by what Go offers in the way of profiling and performance observability baked into the language. I know tools to do benchmarking and profiling exist for other languages, but the fact that a lot of that data is "in the box" for Go is incredibly convenient, to the point where any API I develop has a flag to enable serving pprof data.
