### Bun on Linux x64
Bun is now available for Linux x64. That includes a filesystem watcher leveraging `inotify`, Linux's API for watching files as well as macros and SSR/SSG.
When bundling 20 copies of Three.js on Linux x64, Bun performed:
- 1.6x faster than esbuild
- 13.5x faster than Parcel 2
- 19.5x faster than Webpack (without `babel-loader`)
I have done very little work on optimizing Bun for Linux. I'm not satisfied with these numbers, but it's a start.

<sup>Bun uses the `GOMAXPROCS` to control concurrency despite not being written in Go because I didn't want to think about what to name the variable</sup>
The runs with `GOMAXPROCS=1` are single-threaded runs.
Bun single-threaded performed 2.2x faster than esbuild single-threaded. The relative gap between single-threaded and concurrent performance implies there's room for improvement in Bun's concurrency code. This machine has 6 cores (`nproc` returns `12`) and 64 GB of memory.
