This talk will dive deep into the internals of one of the fastest growing profiling gems: Pyroscope. Pyroscope is unique because it is actually a ruby gem of another ruby gem written in rust; Pyroscope extends the popular rbspy project as a foundation to not only collect profiling data, but also to tag and analyze that data as well. You can think of Pyroscope as what you would get if rbspy and speedscope had a baby. We’ll start with the internals and end with an example of how two flamegraphs can be used to tell a story about your applications performance.
