Spinlocks: reducing context switches without ignoring contention
A September 11, 2026 article on spinlock optimization: keeping threads busy on the CPU can avoid system calls and context switches, but performance trade-offs need evaluation.

What happened and what to do
Published on September 11, 2026, the article covers spinlock optimization, a mechanism that keeps threads on the CPU rather than yielding to the scheduler. Its preview notes that this approach can avoid system calls and context switches; evaluating performance trade-offs matters to engineers considering its use.
A company can measure contention, latency, and CPU consumption in its services' critical paths before choosing between spinlocks and mechanisms that yield execution. Wendelmaques can help instrument these components, build performance tests and dashboards, and support decisions with data from the actual environment.
How the consultancy can help
Wendelmaques can diagnose contention points and performance goals, scope instrumentation and testing, and implement and operate the required data collection and dashboards.
