Cloudflare optimized Big Pineapple's DNS cache storage, reducing per-entry footprint by over 50% through five successive changes, freeing ~100TB of memory across their fleet. The optimizations also improved performance: insert throughput rose 43% and lookup latency dropped 19%, thanks to fewer allocations and better memory locality.
