New ("ring buffer is full") ) Provides MPMC, SPMC, MPSC, and SPSC ring buffers. 10 :: 7 min read I learned a bit of Haskell read more → How to fix a bug in the Linux kernel 2022. This queue is designed for low-latency and high-concurrency scenarios, making it ideal for use in real-time systems, multithreaded applications, and other performance-critical environments. Nov 8, 2025 · Multi-Producer Multi-Consumer (MPMC) Ring Buffer SPSC was simple — one producer, one consumer. ⚡ Features 🔄 Lock-Free Ring Buffers SPSC - Single Producer Single Consumer (~5ns latency) MPSC - Multi Producer Single Consumer MPMC - Multi Producer Multi Consumer Cache-line aligned to prevent false sharing Power-of-2 sizing for branchless modulo Bulk operations for batching Lock-Free MPMC Ring Buffer. But in real world, you may have: Multiple threads producing work (market feeds, logs, tasks) I have always found MPMC ring buffers to have worse tails than pointer-based MPMC queues. A C-based soft real-time event processing engine exploring scheduling, concurrency, and deadline-aware design on Linux. Similarly, a circular buffer that only allocates on construction can be used, which eliminates dynamic memory management when pushing or popping values on or off the queue.
