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

I just hope this kind of fanatic feeling.Abbreviation (abbreviations ):The abbreviation is used in insert, replace, and command line mode. If you enter a abbreviated word, It will be replaced with the represented word. This allows you to reduce the number of times you enter long words. It can also be used to automatically correct freq

AB's full name is Apache Bench, which is Apache's own network stress test tool, which is the simplest and most versatile of the Http stress testing tools I know compared to LR and JMeter.The AB command is very low on the computer that emits the load, does not consume very high CPU and memory, but can also generate a huge load on the target server, which can achieve the basic stress test.In the case of stress testing, it is best to use the switch direc

1, AB command principleApache's AB commands simulate multi-threaded concurrent requests, test server load pressures, and test the pressure of Nginx, Lighthttp, IIS and other Web servers.The AB command is very low on the computer that emits the load, does not consume a lot of CPU, and does not take up too much memory, but it can cause huge load to the target serve

contains the corresponding percentage (in subtle units) of time that is required to process requests for each corresponding percentage (from 1% to 100%). This format is more useful than the ' gnuplot ' format because it is "binary".-G writes all test results to a ' gnuplot ' or a TSV (tab-delimited) file. This file can be easily imported into Gnuplot,idl,mathematica,igor or even Excel. One of the first behavior headings.-I executes the head request instead of get.-K enables the HTTP keepalive f

The server load is too large to affect program efficiency is very common, the Apache server with a tool called AB (Apachebench) in the bin directory. AB is dedicated to HTTP server benchmark testing, which can simulate multiple concurrent requests at the same time, using this lightweight tool we can load test the server. Today in the company also use it to do some testing, now sorted out some of its things
