This is code is a bit rough in the sense that I have taken shortcuts to quickly iterate. This is not ready for merging yet, but I think it's already useful for people that want to generate flamegraphs for things as large as NixOS. Usage: NIX_PROFILE_FILE=/tmp/nixos-trace nix eval -v --no-eval-cache .#nixosConfigurations.turingmachine.config.system.build.toplevel The result can be imported in tools that support folded stacks i.e. https://www.speedscope.app/ or the original flamegraph script (https://github.com/brendangregg/FlameGraph) The profiler records stack trace of the nix evaluation every 10ms (100Hz). The resulting file is 1.9GB uncompressed and 5.4MB compressed with zstd. Change-Id: I3484d3bd832e612747d02c251f2763e0c133a5dc |
