SPSC ring buffers: synchronization and cache
A March 28, 2026 article examines optimizing an SPSC ring buffer, comparing mutexes, atomics, and cache-focused changes to reduce contention.

What happened and what to do
Published on March 28, 2026, the article describes optimizing a single-producer, single-consumer (SPSC) ring buffer. The process moves from mutexes to atomics and includes changes to memory ordering and cache-focused adjustments. It reports performance at each stage and a reduction in cache-line ping-pong, highlighting how synchronization choices and cache-line contention affect results.
A company relying on low-latency queues can apply this type of analysis to its own systems: measure performance under representative workloads, identify contention, and compare synchronization alternatives. Implementation could include reproducible benchmarks, latency and throughput monitoring, and documented criteria for selecting an approach suited to the workload.
How the consultancy can help
Wendelmaques can diagnose bottlenecks in queues and concurrent systems, scope benchmarks and instrumentation, and implement synchronization and monitoring improvements on the company’s infrastructure.
