Introduction # In the world of systems programming, memory management is the ultimate trade-off. Go (Golang) became famous because it abstracted this complexity away from us. The Go Runtime’s Garbage Collector (GC) is a marvel of engineering—it is concurrent, tri-color, and, as of 2025, incredibly efficient with sub-millisecond pause times for most workloads.
