Why do performance tests?

Let’s take a look at some statistics:

  • 71% expect web pages to open as fast on their phones as they do on their computers.
  • Five seconds is considered the maximum user response time, and 50% of mobile users give up if the response time is longer than five seconds.
  • 33% disappointed users will use competing products instead;
  • Three times a user tries the same performance problem, 50% of them will never use the app again.

What is Web Performance Testing?

Performance testing, in short, is a process that mimics the user’s operation on a system in large quantities, obtains the performance indicators and performance bottlenecks of the system, and finds the existing problems, and then optimizes them with the assistance of multiple users.

In the performance test on the Web side, you should pay attention to the following indicators: user operation response time, system throughput (TPS), system hardware resources (CPU, hard disk, disk), network resource usage, and so on.

A lot of people have been asking me for information on Web performance testing recently, so I rummaged through my closet and found this classic ebook, “Implementing Web Performance Testing at No Cost — Based on Apache JMeter.”

Information on

This book is a hands-on book on Web performance testing, starting with the basic theory of performance testing and then detailing how to use JMeter to perform various types of performance testing. In the practical section, the author takes the example of testing the telemarketing system of a large insurance company and teaches the reader how to use JMeter to perform a practical performance test. This book is rich in content, knowledge points explained thoroughly, suitable for software engineers reference learning.
