摘要
Web服务器的性能对许多公司和组织的成功至关重要。然而，很少有人发表定量研究服务器行为和确定性能瓶颈的结果。在本文中，我们测量并分析了流行的Apache Web服务器在一个单处理器系统和一个运行IBM AIX操作系统的4 cpu SMP(对称多处理器)系统上的行为。使用AIX内置跟踪工具，我们获得了运行由SPECweb96和WebStone基准测试驱动的Apache时的内核事件和系统活动的详细信息。在定量地确定性能瓶颈之后，我们提出并实现了6项技术，这些技术将Apache的吞吐量提高了61%。这些技术是通用的，也可以应用于其他Web服务器。
Measurement, analysis and performance improvement of the Apache Web server
Performance of Web servers is critical to the success of many corporations and organizations. However, very few results have been published that quantitatively study the server behavior and identify the performance bottlenecks. In this paper we measured and analyzed the behavior of the popular Apache Web server on a uniprocessor system and a 4-CPU SMP (Symmetric Multi-Processor) system running the IBM AIX operating system. Using the AIX built-in tracing facility, we obtained detailed information on kernel events and system activities while running Apache driven by the SPECweb96 and the WebStone benchmarks. After quantitatively identifying the performance bottlenecks, we proposed and implemented 6 techniques that improve the throughput of Apache by 61%. These techniques are general purpose and can be applied to other Web servers as well.
