Drupal stress tool

With SOAtest from Parasoft, you can automate complete end-to-end testing for both business- and security-critical transactions. APImetrics documentation can be found here. A library injection technique that employs the concept of reflective programming, Reflective DLL injection performs the loading of a library from memory into a host process.

Check out the documentation on GitHub. A user-friendly tool for web application load testing and performance testing, LoadTracer works like many other load testing tools, recording scripts and playback with hundreds of virtual users. The full documentation can be found at SourceForge.

Test earlier and more often with Rational Performance Tester, which validates web and web server applications for scalability, identifies bottlenecks, and more.

An Open Source Java-based framework that you can incorporate into your applications for performance testing, J-hawk generates performance reports to help you identify bottlenecks. Check out our Selenium tutorial! With Performance Center from HP, you can plan and execute tests across multiple global projects. With software testing tools and consistent processes, you can create a world-class testing center with ease. A web site coverage, HTTP load generator, HTTP benchmarking, and stress testing tool, Hammerhead is designed to emulate several users from different IP addresses at maximum speeds to push your apps to the limit.

Load Xen, by Testcollab, enables you to simulate millions of requests to help you more effectively scale your applications. You can create interactions that seem just like real users to your application, randomize requests, run concurrent tests, and more with Load Xen. There are many options available ranging from open source to enterprise-ready tools to perform load testing. We hope this list will help you choose the right load testing tool for your project depending on the kind of software you are building and your budget.

Data transferred is the sum of data transferred to every siege simulated user. It includes the header information as well as content. Because it includes header information, the number reported by siege will be larger then the number reported by the server.

In internet mode, which hits random URLs in a configuration file, this number is expected to vary from run to run. Transaction rate is the average number of transactions the server was able to handle per second, in a nutshell: transactions divided by elapsed time. Throughput is the average number of bytes transferred every second from the server to all the simulated users.

Concurrency is average number of simultaneous connections, a number which rises as server performance decreases. Successful transactions is the number of times the server returned a code less then Accordingly, redirects are considered successful transactions. Create a text file called urls. Now you can start siege and provide the path to the file you created, to start a test against those URLs:.

Internet mode is another interesting option in Siege, in which each the URLs that a user hits in the test is randomized.

This mimics a real-life situation in which you can't predict which URL a person will visit on your site. The other implication of this option is that there is no guarantee that each page in the URLs text file will be hit, due to the randomization. To start a Siege in internet mode, use the following command, again passing in the path of your urls.

Concurrent users requires argument : This option allows the user to stress the web server with NUM number of simulated users. The amount is limited only by the computing resources available, but realistically a couple of hundred simulated users is equal to many times that that number in actual user sessions. If you are comfortable with the UNIX command line and you should not be afraid of the shell , you will likely already know several of these tools.

Learn them, love them. There are a few kinds of tests you can perform: usually a fixed number of total requests or variable connections over a fixed amount of time.

To answer, "How may requests per minute can we handle? To simulate being " Dugg " or " slashdotted ", you want to increase the number of concurrent connections and see how fast your server can return several thousand pages. The information ab feeds to you is one of the metrics that can help you get a high-level view of how your site and server will perform when they are under heavy load.

If you have a particular page you care about, say example. If you want to simulate actual logged-in users, you will have to send cookie data, which is easy to do with ab. Keep your CSS and JavaScript aggregation turned on if you plan on using those in your production environment. If your theme doesn't do this already, put Stylesheets at the top and JavaScript at the bottom. Wow this is incredibly useful! I will definitely bookmarking this page as suggested.

I appreciate that you compiled the tools and 'vocab' terms here for beginners, this should help out a ton in analyzing my work. Wondering why you specified to "turn off your page caching" -- wouldn't you want to stress test with your page caching on if your site is largely read-only for anon users and you plan to enable page caching? Testing your site's performance There are several ways to test, and a few metrics to acquaint yourself with.

Useful Vocabulary Words The concepts involved with testing a site don't always overlap with developing, administering and theming a site, so here is a glossary of useful performance vocabulary words. Execution Time The amount of time your Apache server takes to create the output of the page. Page Load Time The duration from when the client sends a request to the server, until it receives the end of the page. Server Utilization Many sites will measure their utilization during normal times of traffic, but also during spikes in traffic.

Can you believe it? This is useful for figuring out if you may need a new Index see below or if your querying skills are not ninja-level.

Database Indexes If you're querying a particular row in a database table without indexes, the database server has to work a lot harder to find that specific row. Then what is the URL of that first item? Fortunately, Gatling gives us the ability to parse the result and use it in the next request this way:.

Until now, what we have done behaves exactly like a browser-based automated test. In the end, we defined how and what should be downloaded via HTTP requests, indeed using a novel syntax. We have our httpProtocol and the scn scenario, we can now ask Gatling to create some users and gradually put more pressure on the site and the infrastructure:. In this scenario, we ask Gatling - over the course of 10 seconds - to add 10 users.

There are many strategies that Gatling can follow when injecting new sessions to the simulation. During the implementation of your test, you surely want to execute it locally, a little script can be convenient, especially if you are not alone on your project:. The HTML report is detailed and ready to show even for business stakeholders, along with your expert insights:.

Optionally, if you aim for realistic, large-scale executions of this test, we can put it in the cloud. The ingredients here are:. After this, you can upload the simulation files as Taurus tests , and do a little configuration:. Moreover without extra effort, you can trivially make sure that the test is not bound by the infrastructure:.

There is a lazy way to be able to record simulation using a GUI, if you just start to experiment with Gatling. Try it out, but for any non-trivial tests, you need to touch the Scala code. So you just developed a neat, complex stress test suite for your intranet and you have a plan to maintain it alongside your core project.
