Motivation
Using a thread pool to distribute the SSG load over multiple workers can significantly improve the SSG execution time. According to my local tests (Mac M3 Pro), SSG can be divided by ~2 and probably more if there are enough pathnames to render.
This build benchmark only reports a 15% improvement because SSG is only a part of the full Docusaurus build. The SSG time went from 11s to 5s locally so it remains significant, and will feel even more significant once we activate Rspack persistent caching.
Note: we'll have to fine-tune the thread pool settings, create sensible defaults, and expose an API to customize settings.
Note: This is only a POC used to measure the impact. To merge this, we'll need to do a breaking change, because the Helmet unserializable data structure prevents the usage of worker threads. I removed the Helmet data for this POC, but it is a critical piece for Docusaurus SEO.
