Xperfs

Xperfs is a cross-platform benchmarking framework designed to quantify and compare the performance characteristics of computer systems, software applications, and workloads. It provides a library of standardized tests, measurement tools, and reporting capabilities intended to improve reproducibility and comparability across hardware and software environments.

Its architecture centers on a modular test suite, a configuration scheme, a results database, and a command-line interface. Tests cover processor and memory subsystems, storage I/O, graphics, and representative application workloads, including web services and machine learning tasks. The framework supports containerization and virtualization, enabling isolated, repeatable experiments on Linux, Windows, and macOS, as well as cloud environments.

Metrics and methodology: Xperfs emphasizes reproducible measurement through fixed random seeds, versioned benchmarks, and documented environment specifications. It reports throughput, latency, energy efficiency, and variance, and can deliver aggregated summaries and per-test detail. Results may be exported as JSON, CSV, or rendered in built-in dashboards or external BI tools.

Development and governance: Xperfs emerged in the early 2020s as an open-source project developed by a diverse community of researchers and engineers to address inconsistencies in prior benchmarking efforts. It is maintained by an international contributor base with public issue trackers, code reviews, and contribution guidelines.

Impact and usage: The framework is used by academic researchers, hardware vendors, cloud providers, and software developers to compare configurations, validate performance claims, and guide optimization work. It promotes open benchmarks, transparent methodologies, and reproducible results.
