This article explains Go's memory allocator by comparing it with the Linux kernel SLAB allocator, detailing the page‑heap (mheap), span structures, per‑P caches (mcache), and the mallocgc path for small and large allocations, while showing key source code snippets and diagrams.
This article provides a detailed technical analysis of Go's runtime memory management, covering the initialization of the mheap structure, small‑object allocation via mcache, large‑object handling, the three‑color mark‑and‑sweep garbage collector, memory release mechanisms, and the optimization techniques that coordinate mcache and mheap for efficient concurrent execution.
This article examines Go's memory allocation mechanisms in version 1.12.6, detailing the roles of spans, mcache, mcentral, and mheap, explaining tiny, small, and large object handling, and describing GC and heap reclamation improvements for efficient runtime performance.
