Description

Do you want to request a feature or report a bug? feature

What is the expected behavior?

Would be cool to experiment and see if fetch phase becomes faster if we do fetch/unzip to cache using workers.

Research direction
Investigate the existing fetch and unzip logic in Yarn's source code (likely in src/package fetcher.js or similar). Look into using Node.js worker threads to parallelize fetching and unzipping. Check if any earlier attempts or discussions exist in the comments (3 comments, none visible). Determine if this is feasible given Yarn v1's architecture and frozen status.
