Evolution of Garbage Collection in Go: From Mark‑Sweep to Hybrid Write Barriers

This article explains how Go's garbage collection has progressed from the simple stop‑the‑world mark‑and‑sweep algorithm in Go 1.3, through the tri‑color concurrent marking with insert and delete write barriers in Go 1.5, to the hybrid write‑barrier approach introduced in Go 1.8 that dramatically reduces pause times while preserving memory safety.

Golang Garbage Collection: Algorithms, Memory Management, and Evolution

The article details Go’s runtime memory architecture—including pages, spans, mcache, and size classes—and explains its non‑generational concurrent tri‑color mark‑and‑sweep garbage collector, the required write‑barrier techniques, and the collector’s evolution, phases, trigger mechanisms, and practical code examples across Go 1.0‑1.16.

In‑Depth Study of Go’s Garbage Collection Algorithm and Its Evolution

This article provides a comprehensive analysis of Go’s non‑generational concurrent mark‑and‑sweep garbage collector, tracing its evolution from early stop‑the‑world implementations to the mixed write‑barrier design in Go 1.8, and explains how to interpret GC traces, tune GC parameters, and reduce latency caused by mark‑assist and STW pauses.
