In this stream, we started porting parts of the flamegraph profiling tool to Rust: http://www.brendangregg.com/flamegraphs.html. In this part, we focused on figuring out how the tool works, and on porting the stackcollapse-perf script that does most of the heavy-lifting: https://github.com/brendangregg/FlameGraph/blob/master/stackcollapse-perf.pl. Towards the end, we have an almost complete port of that script that is ~10x faster than the original! You can see the repository for the Rust port at https://github.com/jonhoo/inferno.
