Daniel Rosenwasser introduces a native port written in Go that brings 8x to 12x speedups on full builds, dropping VS Code compilation from 125.7 to 10.6 seconds. It parallelizes work through --checkers and --builders flags, rebuilds file-watching on Parcel’s watcher, cuts memory use by 6-26%, and stabilizes the language server with 60% fewer crashes. Framework tooling like Vue, Astro, and Angular waits for a stable API in 7.1.
