ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.
Apache Bench (ab) is a load testing and benchmarking tool for Hypertext Transfer Protocol (HTTP) server. It can be run from command line and it is very simple to use. A quick load testing output can be obtained in just one minute. As it does not need too much familiarity with load and performance testing concepts, therefore it is suitable for beginners and intermediate users. To use this tool, no complex setup is required. Moreover, it gets installed automatically with Apache web server, or it can be installed separately as Apache utility. It does not have all the features of more popular tools such as jMeter or Grinder, but it is good for a start.
Before proceeding with this tutorial, you should have a basic understanding of command line interface (CLI), HTTP, text editor and web servers, etc., because you will need these tools to successfully run Apache Bench for load testing. In addition, it will be good if you have knowledge of web development and application testing processes.
ApacheBench (ab is the real program file name) is a single-threaded command line computer program used for benchmarking (measuring the performance of) HTTP web servers.[1] Originally it was used to test the Apache HTTP Server but it is generic enough to test any web server supporting HTTP/1.0 or HTTP/1.1 protocol versions.
The ab tool is written in C and it comes bundled with the standard Apache source distribution, and like the Apache web server itself, is free, open source software and distributed under the terms of the Apache License.
Note that ApacheBench will only use one operating system thread regardless of the concurrency level (specified by the -c parameter). In some cases, especially when benchmarking high-capacity servers, a single instance of ApacheBench can itself be a bottleneck. When using ApacheBench on hardware with multiple processor cores, additional instances of ApacheBench may be used in parallel to more fully saturate the target URL.
The ab command also known as ApacheBench is a command line benchmarking tool for testing the amount of time it takes your server to respond to HTTP requests. You can use this information to determine the estimated number of simultaneous requests your Apache HTTP server can handle before it begins to degrade the overall performance.
Apache Benchmark (ab) is a CLI-tool which comes with the Apache HTTP server (HTTPD). To follow the example in the blog post, make sure you have installed the Apache HTTP Server on your machine and the ab binary is available on your PATH:
Provides some add-on programs useful for any web server. These include: - ab (Apache benchmark tool) - fcgistarter (Start a FastCGI program) - logresolve (Resolve IP addresses to hostnames in logfiles) - htpasswd (Manipulate basic authentication files) - htdigest (Manipulate digest authentication files) - htdbm (Manipulate basic authentication files in DBM format, using APR) - htcacheclean (Clean up the disk cache) - rotatelogs (Periodically stop writing to a logfile and open a new one) - split-logfile (Split a single log including multiple vhosts) - checkgid (Checks whether the caller can setgid to the specified group) - check_forensic (Extract mod_log_forensic output from Apache log files) - httxt2dbm (Generate dbm files for use with RewriteMap) Tags: System Administration: Configuration Tool, Software Development: Perl Development, Libraries, Implemented in: implemented-in::c, implemented-in::perl, User Interface: Command Line, Networking: network::service, protocol::http, Network Protocol: IPv6, Role: Development Library, role::program, scope::utility, Security: Authentication, Application Suite: suite::apache, works-with-format::html, Works with: Text
Web Server performance testing and benchmarking are essential to understand the load capacity of a web app. The tools highlighted in this article will help you effectively perform load testing and HTTP benchmarking on your web application.
To perform load testing and HTTP benchmarking for your application, you need to use tools designed for that purpose. We have highlighted 10 of the most efficient and widely used HTTP benchmarking and load testing tools in this article.
Autocannon is a wrk-influenced HTTP benchmarking tool written in node.js. It supports HTTPS and HTTP pipelining and can be used programmatically through an API and as an independent command-line tool.
h2load is a benchmarking tool for HTTP/1 and HTTP/2 with support for SSL and TLS connections. It is a tool built by nghttp2, and it is compiled alongside nghttp2, specifying --enable-app flag and installing the required dependencies.
For the purposes of this manual page, we are focusing on the use of ab, the Apache HTTP server benchmarking tool. ab is often found pre installed with many Gnu/Linux distributions, and is designed to give you an impression of how your current Apache installation performs.
For Windows users, the ab tool can usually be found somewhere in the installation path of your Apache-based web server. For example, in WAMP it can be found in c://bin/apache/Apache/bin. Using the Windows command prompt (accessible by going to "Start", "Run" and typing "cmd"), navigate to the directory containing ab and then you can use the tool as outlined in the examples below. Alternatively, you can place the path to Apache's bin folder in your PATH variable, thus making the ab tool accessible without the need to navigate to it's directory every time you launch the command prompt.
I am encountering a performance issue with Elasticsearch in Amazon EC2.
Currently I am getting at most 500 rps using ab - Apache HTTP server
benchmarking tool with a very simple query. Our goal is to get to atleast
1000 rps, but it seems unlikely unless we throw more hardware at it. Any
advice would be greatly appreciated.
We chose to use the ApacheBench application as our command-line-based benchmarking tool. The application is well established and documented and is a reliable test. You could replicate these results at home with our servers if you wanted to. While ApacheBench was initially created to benchmark and test Apache Web Servers, the application is suitable for testing on any web server, like Nginx or LiteSpeed.
One concern I might have is that total page size and request count changes. Why? Did you configure some caching/compression on the litespeed and not on the nginx/apache making it just plainly unfair to those servers?
In this recipe, we will learn some performance tuning configurations that may help to squeeze out the last bit of performance from the available hardware. Before diving into performance tuning, we need to evaluate our servers and set a benchmark which can be used to measure improvements after any changes. We will be using a well known HTTP benchmarking tool, Apache Bench (ab). Various other benchmarking tools are available and each one has its own feature set. You can choose the one that best suits your needs.
Web server benchmarking is useful in testing your infrastructure to see if it can withstand expected visitor growth and maintain a reasonable response under load (i.e. requests per sec, latency, bandwidth).
Apache bench (also called Apache benchmark) is a useful load testing tool for websites that run on Apache web server. It is easy to install, and allows you to simulate & test different kinds of website loads, to enable your website to cope with real-world situations. In this article, we will look at how to install, configure & use Apache bench for load testing. We will also look at how to interpret Apache bench results.
Also, notice the list of private and public hostnames of the experiment nodesincluded in the instructions. You will use the public hostnames (shown in bold)in the exercise with the Apache web server and apache benchmark.
Benchmarking a web application is really twofold: You should test how well the server hardware performs and in this way better choose a correct hardware profile for your needs as well as help you optimize your server-side code (typically PHP code). Next you can then turn to front-end testing tools which look at how quickly your website renders in the user (client) browser. Read more about these front-end testing tools at the end of this article.
While benchmarking your target web server it is a good idea to have a seperate console window open and running something like htop or similar tool which gives you an overview of what your target web server system is doing. If you for example experience that when doing lots of simultaneous requests against your php application you notice RAM filling up to 100% and then the request speed taking a nosedive, this is a good indication of where that specific VPS instance has a bottleneck. If you want to serve more requests faster, you would need more RAM or optimize your application to use less memory
