core-to-core-latency-plus is a utility tool designed for Windows that measures the communication latency between CPU cores. This application focuses on fixing two threads on different CPU cores and utilizes a series of compare-and-swap operations to gauge latency effectively. By leveraging the CPU cache coherence protocol, it provides accurate insights into the performance dynamics between cores, making it a valuable resource for users interested in hardware performance metrics.

This software is a fork of the original nviennot/core-to-core-latency, with enhancements aimed at improving usability and expanding the collection of CPU benchmark data. As a free tool categorized under Utilities & Tools, core-to-core-latency-plus is particularly useful for developers and performance analysts looking to optimize CPU utilization and understand the latency implications of multi-core processing.
