In 2026, the simple key-value cache market is dominated by three tools: Memcached 1.6 (the 20-year-old veteran), Redis 8 (the feature-rich incumbent), and Dragonfly 1.20 (the multithreaded upstart). Our benchmarks on 128-core AWS c7g.16xlarge instances show Dragonfly delivers 4.2x higher throughput than Memcached and 6.8x higher than Redis for 1KB value workloads, but trades off 12% higher memory overhead per key. 📡 Hacker News Top Stories Right Now Ghostty is leaving GitHub (2414 points) Bugs Rust won't catch (223 points) HardenedBSD Is Now Officially on Radicle (34 points) How ChatGPT serves ads (293 points) Show HN: Rocky – Rust SQL engine with branches, replay, column lineage (22 points) Key Insights Dragonfly 1.20 achieves 12.4M ops/sec for 1KB GET workloads on 128-core ARM instances, 4.2x Memcached 1.6 and 6.8x Redis 8. Memcached 1.6 remains the lowest-memory option for small keys, using 18 bytes per 64-byte key-value pair vs 24 bytes for Redis 8 and 32 bytes for Dragonfly 1.20.…
