AB is a very useful test tool for Apache, and when you're done with Apache, you can find AB below the bin. Parameter descriptions and examples We can simulate 100 concurrent users and send 1000 requests to a page. Input command: ab-n1000-c100 http://www.jb51.net/ Where-n represents the number of requests,-C represents the number of concurrent return Resu

First, the principle of ABAB is the abbreviation for the Apachebench command. Ab ab style= " font-family:calibri;">url address to access. Its test target is based on the url So it can be used to test apache load pressure, can also test nginx lighthttp , tomcat , iis web The AB command is very low on the computer that emits the load, and it

Open the installation path of the Apache server (I use wampserver), there is a Ab.exe executable program in the bin directory, it is the stress test tool to be introduced.Under the Windows System command line, go to the directory where the Ab.exe program is located and execute the Ab.exe program.

At present, most testers like to use Loadrunner with a graphical interface as a web performance testing tool. In fact, there are many open-source performance testing tools on Linux systems that are very small and open-source products. It is a good choice for testers. In the past, we used the AB tool for some time during web performance testing, At present, most testers like to use Loadrunner with a graphical interface as a web performance testing tool

AB is a common performance testing tool because it supports windows ...The commonly used commands are ab–c–n–k-r, respectively: The number of analog terminals, the number of packets sent, whether the request is keepalive, ignoring the error, the default is to get the request, that is, the following request can be tested with it:There's no more talking here.Second, this is mainly said to test the post method

Use AB to stress test the site, start setting concurrency 500, can be used normally, when the set concurrency is 1000, then the error: Apr_socket_recv:connection Reset by Peer (104) To change the server Apache maxclients parameters, the maximum number of open files, do not solve the problem, finally found is because AB's source code on the concurrency of AB limit, modify the source code to recompile

AB is the abbreviation for apachebench.The AB command creates multiple 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 comput

Apache AB commandI. Introduction AB is a stress testing tool provided by apache. AB is very practical. It can not only perform Website access stress tests on apache servers, but also perform stress tests on other types of servers. For example, nginx, tomcat, and IIS. Ii.

Recently in doing webservices, the data obtained is from the German side of the server. To integrate this data into the current Web site. Do not know how performance. Just do a stress test. Now some of the stress testing tools are charged. Bring a AB tool in the open source Apache. It's in C:\Apache2.2\bin\ab.exe. Use it to detect how your program is performing. Use it. , you can improve your code quality. The Apache Bin directory. format.

Recently, a test was conducted on the new architecture of jujuya, with 200 requests and 20 concurrent requests. this test intensity accounts for 70-80% of the CPU, and w3p occupies more than 70 MB of memory. I want to test it several times to see if its memory will increase. I can't help without a test machine, developers need to work. I guess there is a problem with the CPU and performance needs to be optimized. Mark the usage of the testing tool by the way Basic usage :

Throughput Rate IntroductionWhat is the throughput rate, explained, is the number of requests processed by the server in the unit time, this may be our measure of a Web site is a very important indicator, when 10 users simultaneously initiated 100 requests and 1 users simultaneously to the server to initiate 1000 requests, our effect is not the same, Here is a concept to illustrate that the continuous request means that a user's request is made through the server and returns to the next request,
