Avaliação de métricas de desempenho entre WSL 2 e Linux nativo na execução de Benchmarks científicos

Abstract

This work evaluates the performance of Windows Subsystem for Linux version 2 (WSL 2) in comparison with the native Linux environment, with a focus on the execution of scientific applications. The growing adoption of WSL by researchers and developers justifies the analysis of its viability under intensive computational workloads. The adopted methodology was based on the application of three widely recognized synthetic benchmarks — SA-HPL, STREAM, and IOzone — to measure specific performance metrics: execution time, floating-point operations per second (FLOPS), memory bandwidth, and I/O throughput. The tests were conducted on identical hardware, with standardized configurations to ensure comparability. The results showed that native Linux outperforms WSL 2 across all evaluated metrics, especially in scenarios involving high concurrency and intensive write operations. WSL 2, in turn, demonstrated satisfactory performance under light loads and read operations, standing out for its integration with Windows and ease of use. It is concluded that, although it presents performance limitations, WSL 2 can be a viable alternative for educational purposes, testing, and prototyping in scientific environments.
