How to change the performance of the web application server?

Web performance has become an important criterion for judging the success of a website. Web servers are an important part of determining web performance.

Web server performance refers to the ability of a web server to respond to user requests. In order to improve the performance of the Web server, people have made many attempts and have achieved gratifying results. This paper proposes a method and strategy for optimizing the Web server in a specific application environment by analyzing the results of previous research.

Factors Affecting Web Application Server Performance

Web server performance refers to the ability of a Web server to respond to user requests. Server performance is critical to a Web system. Many attempts have been made to improve the performance of Web servers, and many techniques and methods have been adopted, but these techniques and methods often lack applicability.

Through the analysis of previous studies, it can be found that there are two main reasons for this problem in the optimization of web server: one is the performance evaluation of the server, and the other is the optimization scheme. Consider the incompleteness.

The current server performance evaluation tool is actually a one or several computer simulation clients that communicate with the measured web server when evaluating the web server. Environment, this is a certain difference from the real WAN environment.

In addition, when the evaluation tool selects the network load, it is as close as possible to the real load, but there is still a gap with the continuous high frequency load requirement; in addition, the selection and analysis of the performance test indicators are also Not reasonable enough, resulting in unfair and reliable analysis results. When choosing the method of optimizing the web server, it is often only considering one aspect of the web server, and rarely combining the specific application environment. Therefore, the evaluation results are not scientific enough, the application environment considerations are not comprehensive enough, and the performance optimization of the Web server is not targeted. Therefore, optimizing the performance of the Web server in a specific application environment requires two additional considerations: network characteristics and Web load characteristics.

Network characteristics refer to the network situation of the web server, whether it is a wide area network or a local area network, a high-speed network (a network with a transmission rate above 1OOMb/s is called a high-speed network) or a low-speed network, which is related in different networks. The network characteristics such as the type of data to be transmitted, the corresponding time of the network, the throughput, and the utilization rate are not the same, so it is necessary to distinguish it, and analyze the specific situation.

In terms of Web load characteristics, a very critical factor in the evaluation of Web servers is the choice of Web load. Although there are many evaluation tools, they all do their homework on the selection load. The main purpose of the research on the characteristics of Web load is to evaluate the performance of the Web server. Based on these characteristics, you can choose the evaluation tool that simulates the most realistic Web load to get the most relevant Web server performance evaluation data, so that you can better It analyzes and derives an optimization plan.
