  "summary": "In high-performance concurrent systems, real-time audio processing pipelines, and low-latency financial order routers, passing messages between threads using standard mutex-protected queues (std::queue wrapped in std::mutex) introduces severe performance penalties. Mutex locks force kernel context switches, thread blocking, and unpredictable latency spikes. To achieve lock-free inter-thread…",
