Glad to see that there's support for CPU sample flamegraphs in Perfetto now that's on par with Google's internal pprof visualizer as alluded to in the talk. Using the internal visualizer to share Windows ETW traces with colleagues was the primary motivation for developing [EtwToPprof](https://github.com/google/EtwToPprof). Now that perfetto supports this natively, I might look into developing EtwToPerfetto :-)
Fun fact: Perfetto also gained support for the pprof format within the last month :)
It opens a special "aggregate flame graph" view of the profile since pprof does not preserve time information. But it works! We use it for visualizing aggregates across thousands of profiles in production!
