 - `trace.json`: The time spent on each phase of the Rust side is recorded at a granular level using tracing and can be viewed using [ui.perfetto.dev](https://ui.perfetto.dev/).
 - `jscpuprofile.json`: The time spent at each stage on the JavaScript side is recorded at a granular level using [Node.js inspector](https://nodejs.org/dist/latest-v18.x/docs/api/inspector.html) and can be viewed using [speedscope.app](https://www.speedscope.app/).
-- `logging.json`: Includes some logging information that keeps a coarse-grained record of how long each phase of the build took. (Not supported in development mode yet)
