Long Time Consumption in Generating static pages and Collecting build traces during Build

[shockw4ver]

Summary

There are two stages in my project's build process that consume a relatively long time. Firstly, after the Generating static pages stage is completed, it takes a long time before reaching the Collecting build traces stage. Secondly, the Collecting build traces stage itself takes a significant amount of time. So what exactly these two steps entail? And is there any way to speed up these two stages through customization? For example, can I rewrite the relevant logic using Go or Rust?
