Covers the core get-reset-use-return pattern, two common mistakes (forgetting to reset pooled objects and expecting pool persistence across GC cycles), when NOT to use sync.Pool, and a real-world example showing a 31% latency reduction at 10k req/s. Also demonstrates pooling maps using Go 1.21's clear() builtin and advises using pprof to identify allocation hotspots before optimizing. ## Full article daily.dev links to this article rather than hosting it.
