Apache Bench is used for performing the Load Tests. Load test is an important step for measuring the endurance of a web server for an application or website. Thus, a website or any project with a server should perform HTTP Load testing before launching its project. To download and install the Apache Bench on Windows, the binary zip file should be downloaded from one of the distributors below.
To download and install the Apache Bench AB for windows, you should choose the correct binary zip version and modules for your load testing purposes and device. In this example, you will see an Apache Bench installing process for Windows 64bit, from Apache Lounge. According to the output of the Apache Bench usage example, the time per request was MS, and The max spent time for connecting was MS, for processing, it was Simply, we can see the general situation of the webserver for Holisticseo.
There are two different methodologies for taking the output of the Apache Bench load test as a file. An eaxmple of printing Apache Bench load test result is below. Below, you can see an example of Apache Bench load test result as txt file and gnuplot. Ab-viz lets you execute the benchmark multiple times so that the results aren't skewed.
Ab-viz shows you a progress bar with the number of requests that have been completed. Benchmark Summary. The summary tab shows the output of Apache Bench.
Benchmark Response. This tutorial is designed for Application Developers and System Administrators, who are willing to learn Apache Bench in simple and easy steps. This tutorial will give you practical knowledge on Apache Bench, and after completing this tutorial, you will be at an intermediate level of expertise from where you can take yourself to higher level of expertise. Before proceeding with this tutorial, you should have a basic understanding of command line interface CLI , HTTP, text editor and web servers, etc.
In addition, it will be good if you have knowledge of web development and application testing processes. This script hits a target with requests and then generates a small report for each case. Sign up for free to join this conversation on GitHub.

From the safety point of view, it is considered a good practice for system administrator to create a sudo user instead of working as root.
System will prompt for a new password for the user test. You can enter a simple password as we are just testing, and not deploying to the production server.
Usually the sudo command will prompt you to provide the sudo user password; it is recommended not to use complicated password as the process becomes cumbersome. In this section, we will test the Apache. Here -n is the number of requests to perform for the benchmarking session. The default is to just perform a single request which usually leads to non-representative benchmarking results. And -c is the concurrency and denotes the number of multiple requests to perform at a time. Default is one request at a time.
So in this test, Apache Bench will make requests with concurrency 10 to the Apache organization server. We need to understand the different metrics to understand the various output values returned by ab. If no port is given on the command line, this will default to 80 for http and for https. This will only be printed if SSL is used.
If the document length changes during testing, the response is considered an error.
