5. Understanding the Go Runtime: The Garbage Collector (internals-for-interns.com)
In the previous article
we explored the Go scheduler — how goroutines get multiplexed onto OS threads, the GMP model, and all the tricks the runtime uses to keep your cores busy. But there's a fundamental problem we haven't addressed yet: all those goroutines allocate memory, and somebody has to clean it up. That's the garbage collector's job, and that's what we're exploring today.
In this article we'll be looking at the garbage collector as it works in Go 1.26, which introduced the GreenTea GC. If you're using an earlier version of Go, don't worry — the overall structure is the same. The main difference is in the mark phase, and we'll briefly explain how the older approach differs whenever we reach that point. If you want to hear more about GreenTea, Michael Knyszek gave a great talk about it at GopherCon 2025
