How V8’s Scavenger and Mark‑Sweep Algorithms Optimize JavaScript Memory Management

This article explains V8’s generational heap layout, the Scavenger minor‑GC algorithm with its marking, evacuation and pointer‑updating steps, the parallel Scavenger enhancements, the major mark‑and‑sweep collector with optional compaction, and the various triggers that decide when each garbage‑collection phase runs.

Building a Simple malloc and Mark‑Sweep GC for the Linux Kernel

This guide walks through creating a 32‑bit Linux‑kernel memory allocator using a free‑list, implementing morecore and add_to_free_list functions, and then adding a basic mark‑and‑sweep garbage collector that scans heap, BSS, data segments and the stack to reclaim unused blocks.

Java vs Go: A Comparative Analysis of Garbage Collection Algorithms

The article compares Java’s mature, generational garbage collector—using mark‑copy for young objects, mark‑sweep/compact for old, with sophisticated write barriers and fragmentation handling—to Go’s non‑generational, concurrent tri‑color mark‑sweep collector that relies on a span‑based memory pool, TCMalloc optimizations, and simpler root selection.
