So you want to write a sync system for a web app with offline and realtime support? Good luck. You might find the following resources useful.

On a (cached) github action. pnpm7 ±50s (244Mb store cache) / yarn4-nm ±75s (190Mb yarn install cache)
Tests made with pnpm 7+ and yarn 4.0.0rc (node-modules/pnp) based on https://github.com/belgattitude/nextjs-monorepo-example. Tests have been made in a way to evaluate CI performance. There's other perf bench: pnpm or yarn. Conclusions are pretty similar. This benchmark helped to create this yarn install composite action
