✨ Hot from the release press: When using @rolldown.rs and experiencing a slow build, you now see which plugins slow your build down! Note that the reported time is an indication and includes overhead such as Rust-side processing and overhead from the JavaScript event loop.

This will detect slow built-in and third party plugins. In the example below, the project still uses terser for building instead of Oxc, causing slowdown. PS: This will also work in the next @vite.dev 8 beta (or when overriding the @rolldown.rs version from today on) 👀
