go-profiler-notes

This project was started by Felix Geisendörfer after joining Datadog’s Continuous Profiler team in early 2021. Initially it was just a loose collection of markdown files with notes on Go profiling. But over time and thanks to a few contributors, it has developed into one of the most in-depth resources on Go profiling.

In the future, additional topics such as runtime tracing, metrics, heap debugging as well as userland metrics and distributed tracing will be covered as well.
