Performance concern: Preconstruct build slow in large monorepo (Rollup v2 → v4 upgrade?) #622

Hi team,

I'm using Preconstruct to build my TypeScript packages within a large monorepo. The tool has been great overall, but we're noticing that the build process is consistently slow, taking 4–5 minutes for a full build.

I wonder if it would make sense to upgrade to Rollup v4, which now uses a native SWC-based parser and has significant performance improvements (especially in large-scale projects like ours).

Thanks for your work on this tool! Let me know if I can help with further diagnostics or testing.
