Why Go’s GC Skips Scanning Pointer‑Free Objects and How It Boosts Performance
This article explains the Go runtime’s garbage‑collector optimization that skips scanning objects without pointers, describes how the noscan flag is set during memory allocation, shows the code paths that enforce the skip, benchmarks the performance gain, and offers practical tips for applying the technique in real‑world Go programs.
