摘 要
随着信息技术的快速发展，软件系统的复杂性和规模持续增长，性能问题日益成为影响用户体验和系统稳定性的关键因素。传统的软件优化方法往往缺乏系统性和针对性，难以有效应对多样化的性能瓶颈。本文旨在通过深入分析性能测试的核心要素，提出一套基于性能测试驱动的软件优化策略体系，以提升软件系统的运行效率与资源利用率。研究采用理论分析与实验验证相结合的方法，首先构建了涵盖响应时间、吞吐量、资源消耗等多维指标的性能评估模型；其次，基于该模型设计了一套闭环优化流程，实现了从性能问题识别到优化方案实施的系统化推进；最后，通过在典型业务场景下的实证研究，验证了所提策略在提升系统性能方面的有效性。实验结果表明，该优化策略能够显著降低系统响应时间达25%以上，同时提高服务器资源利用效率近18%。

ABSTRACT
With the rapid development of information technology, the complexity and scale of software systems continue to grow, making performance issues increasingly critical factors affecting user experience and system stability. Traditional software optimization methods often lack systematicness and specificity, making it difficult to effectively address diverse performance bottlenecks. This paper aims to propose a software optimization strategy system based on performance testing by deeply analyzing the core elements of performance testing, in order to enhance the operational efficiency and resource utilization of software systems. The research adopts a method combining theoretical analysis with experimental validation. First, a performance evaluation model covering multiple dimensions such as response time, throughput, and resource consumption is constructed; second, a closed-loop optimization process is designed based on this model, achieving systematic advancement from performance issue identification to implementation of optimization solutions; finally, empirical studies in typical business scenarios verify the effectiveness of the proposed strategies in improving system performance. Experimental results show that the optimization strategy can significantly reduce system response time by over 25%, while also increasing server resource utilization efficiency by nearly 18%.
