Bun: bun-v0.0.28 Release

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.

^{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}

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.
