The Performance Testing class enables you to write code to develop good habits of frequent tests and write performance tests. Introduction: It is convenient for the function to be tested to be executed cyclically in the code to automatically calculate the execution time and support multithreading. Usage: PerformanceTest p = new PerformanceTest (); p. setCount (1
When jmeter is used for performance testing, nmon can be used for server monitoring. I. nmon description Nmon is divided into toolkit and analysis package (nmonanalyser) The installation of nmon is very simple. Download the corresponding version based on the server version and install it. Ii. nmon listening 1. Real-time Monitoring Run./nmon to start the nmon tool in the nmon installation directory. After th
The software performance is listed below:01. Is the system response time that the user understands fast enough?02. Is the resource usage of the Application Server reasonable?03. Is the resource usage of the database server reasonable?04. How many users can access the system at most? What is the maximum service throughput?05. Does the system support 24x7 business access?06. Can the system be extended? Which of the following devices can improve system
."Intermediate response time" is the median response time for a period of time, 50% response time, and half of the server response time is below that value and the other half is above that value."90% response Time" 90% of transaction response time is smaller than this value over time. Response to the overall response speed, and the 10% timeout rate above that value. is one of the important indicators used to assess system capacity.Minimum response time for the Min. reflects the fastest processin
