tools are often developed for a specific purpose, so it's a bit grudging to find an open source performance test tool to compare with LoadRunner or qaload. But open source tools also have their advantages: small, lightweight, offering excellent solutions in areas that are good for you. Therefore, we can consider preparing a "open Source Test Toolbox", peacetime use of free time to understand the application of various tools of the environment and purpose, knowledge accumulated slowly after, you

Experience and comparison of AB and JMeter in GET/POST stress testing Introduction: Internet service stress testing is a very important evaluation method. AB, webbench, and jmeter are all popular testing tools in the industry. AB

We have our own servers, and sometimes we need to test how much data our servers can resist, which will help us deploy and configure our servers, and we have our own free performance testing tools in Apache, Ab (Apache bench) in the Apache bin directory, It can simulate multiple concurrent requests, meaning it is primarily used to test how many requests your Apache can handle per second.

The AB tool included with Apache (the PHP environment used in this machine is the WAMP integration environment, the AB tool is located in D:\wamp\bin\apache\Apache2.2.21 \ Bin) is very easy to use, AB can launch test requests locally directly on the Web server, which is critical , because sometimes we need to test only the server's processing performance, and do

Apache's AB accuracy and more persuasive.Qpt-responds to user times per second and response time per connection.The result of the test is mainly to look at these two values. Of course only these two indicators do not complete the performance analysis, we also need to the serverCPU, men to analyze, to draw conclusionsSecond, WebbenchWebbench is a Web site stress testing tool under Linux that can simulate up

Stress testing is a very important task in operation and maintenance. For example, before a Web site online, can withstand the number of visits, in the case of large traffic performance, these data indicators will directly affect the user experience.However, there is a common in stress testing, that is, the results of the stress test and the actual load will not be exactly the same, even if the pressure tes

PS: Site Performance Stress testing is an essential part of the performance tuning process. It is only when the server is under high pressure that it can truly reflect the problems exposed by the various settings. Apache has a self-contained program called AB that can be used for Web site stress testing on Apache or other types of servers.Apachebench Command prin

Apachebench Command principle:The AB command creates many concurrent access threads, simulating multiple visitors accessing a URL address at the same time. Its test target is URL-based, so it can be used to test the load pressure of Apache, as well as other Web servers such as Nginx, Lighthttp, Tomcat, and IIS.The AB command is very low on the computer that emits the load, does not occupy a high CPU, and do

Nginx is famous for its high concurrency and memory saving. I believe most people who install nginx want to know their nginx performance. I would like to share with you the stress testing methods and results of using the AB tool. AB is a performance testing tool for apache and can only install the
