Christian Hergert: Frame pointers and other practical near-term solutions
I’m the author/maintainer of Sysprof. I took over maintainership from Søren Sandmann Pedersen years ago so we could integrate it with GNOME Builder. In the process we really expanded it’s use cases beyond just being a sampling profiler. It is a system-wide profiler that makes it very easy to see what is going on and augment that data with counters, logs, embedded files, marks, custom data sources and more.
