Swapping to time.AppendFormat drops that heap escape to zero — measured 32 B/op saved per request on the hottest read path.⚡ Bolt: Zero-Allocation and Hot-Path Engineering/posts/024-bolt-performance-engineering/Wed, 12 Aug 2026 11:40:41 +0000/posts/024-bolt-performance-engineering/The Bolt mindset codified: no heap escapes in hashing/encoding, deadline amortization cuts SetDeadline ~98%, allocation hotspots hunted by profile. Teaches: zero-escape patterns, measurement contracts, trade-off posture.
