I want to load test the web application that we're working on? Can you name some automated load testing tool for a website developed on asp.net mvc3? I would like to develop it for concurrent 100 users, 200 users and so on. We want to test it with many users and test the load that creates on the application and server.
BTW, we're also running profiler at the same time to find the application bottlenecks so that we can find code that is slow that we can improve.
There are a number of different options; they vary in all kinds of exciting ways.
I use the open source Apache JMeter for this kind of testing - it's not hugely user friendly, but is very powerful once you get used to it, and the lack of licensing restrictions means you can use it in all sorts of configurations.
Some of our projects have glued JMeter into the continuous integration cycle, running performance tests on nightly builds. Some projects need to scale to huge numbers of users, and we use JMeter in the cloud (there are some service providers who can do this too).
it works nicely with Asp.Net MVC apps.
We are currently load testing our MVC application and the external company uses a product called LoadRunner.
However, depending on how intricate your testing is you could use the WebClient class as a base to run your own volume tests.
Web Performance Load Tester works very well with .NET apps. We test a lot of them (disclaimer: I work for Web Performance and am closely involved with the product).
We have integrated with Fiddler load testing tool called StresStimulus

i want to conduct an http flood to a test website that i have designed in Visual Studio 2017. It is an ASP.NET Webforms site, so i want to ask if Apache JMeter is a proper tool for such a project. I have done some research and found from other users that Apache JMeter is having some problems with ASP.NET apps in some cases. So i'm a little confused. Also, i am considering to use two computers, one for running the website, and the other for running the JMeter script, in order to avoid the resource consumption that may lead to inaccurate metrics. Is it possible to succeed the http flood in such a way? Any other suggestions are welcome.
Thanks.
JMeter doesn't have any problems with ASP.NET websites (as well as any other websites), JMeter is backend-agnostic and it knows nothing about server-side technologies stack as it basically gets HTML and Headers from the server.
Just make sure to perform correlation of dynamic parameters like VIEWSTATE, EVENTVALIDATION, etc. and you should be good to go.
With regards to "flood" approach - I would rather recommend implementing real life user scenarios, to wit JMeter test should represent real usage of your web application by the real user using the real browser including business steps (login, browse, search, etc.) and technical side of things (Cookies, embedded resources, headers, cache)
I want to practice performance testing at home using some load testing tool like jmeter. Can anybody tell me some links of websites or applications on which I can practice performance testing by throwing load by load testing tool from home?
It is not a LEGAL way to conduct load/stress test on any live websites/web applications without the permission.
So, you can deploy your own sample application or download sample applications available online and deploy it in your local server like Apache HTTP server or Apache Tomcat etc.
From my knowledge, You can use WebTours sample application from HP LoadRunner as an application to put your load.
Download HP Load Runner community edition from here. free for 50 vusers for life time. You need to create an account in the website.
You can download the webtours application from the HP website (comes with Apache HTTP server, which acts as a Web server).
Setup WebTours as per the instructions here
Confirm the successful installation/configuration by accessing the application from the browser (similar to http://localhost:8080/WebTours). The app is about flight booking (though not in real time ;) ).
Now, you can use the WebTours application as an AUT (Application Under Test)
Either you can continue with Load Runner or download latest JMeter version (3.1 as of now)
JMeter tutorials:

Builiding a Test plan
For Load Runner, there is documentation available in the following link to start with:
http://lrhelp.saas.hpe.com/en/12.53/help/WebHelp/Content/WelcomeContent/c_Welcome.htm
There is community support available managed by HP.
Use the sample applications which ship with the tool
Take your choice of open source application, install them on servers you own, manage and control. Use these applications as targets.
You are welcome to use api.jmeter.ninja. I built it for that purpose. A more formal API declaration is on it''s way but you can start with
http://api.jmeter.ninja/example.html.
http://api.jmeter.ninja/objects.xml
http://api.jmeter.ninja/objects/${OBJECT}.XML
Where ${OBJECT} is taken from the objects.xml page.
Or swap xml for dot json for the same in Jason format.
Exercises/Tutorial is available at http://api.jmeter.ninja/jmeter.pdf
Currently I just use this service for my own training sessions. But I hope to make it more generally available in the near future. There a currently no automatic limits so please just use your common sense and don't run high at throughput for a sustained periods of time. Anything under a total 100k requests is no problem.
Only caveat is that service is provided on a best effort basis at this point. Any abusive/problematic users may be blocked without notice.
I've got a PHP site up and running, and the db is mysql. before launching the site, I would like to test the traffic handling. Now am assuming that there are soe softwares that would simulate the traffic and log the processes running on my site. Any recommendation of software I should use? the traffic doesn't have to be real, but nonetheless, I would like to generate a high traffic to investigate the threshold of the site.
Appreciate the help
You can use Gatling https://github.com/excilys/gatling.
It's a stress tool written in Scala which aims at being more efficient and lighter than Jmeter.
Basically you record a scenario on your website and then run it 'n' times in parallel.
Here is the wiki for more infos https://github.com/excilys/gatling/wiki/Basic-Usage
You can use Jmeter:
It's free.
it's easy to Start with lot of documentation on its Website and on internet
it has a proxy feature to easily create test plan from browser navigation
It is easy to start up processes on other machines. It remote testing, can be done from GUI or console.
The scripts can be written in beanshell, java, or any jsr223 language ( groovy, Javascript, scala, jexl ...)
it has a lot of built- in samplers and thanks to its plugin architecture it's very Easy to add new ones or use any scripting engine to do what's missing
it has great user mailing list
it has very reactive support
it's now a top Level Apache
it can run thousands of users
professional solutions exist to run it from cloud

Performing a Stress Test on Web Application?
Best way to stress test a website
How do you test the performance of a website?
How is the community handling performance testing of their secured web areas? We don't particularly have a public facing web site, thus users have to be logged into be able view data / access the system. To further complicate matters, we can not allow users to be logged in multiple times -- if you attempt to login a second time your first session is invalidated. We could turn this feature off (as well as second-level caching), but then we are testing a system which is inherently different from production.
What methodologies should we look into to stress test our application?
Our developers are pretty proficient with Java and Python.
Good question.
Normally we'd use something like Selenium to automate a web-browser talking to the web application itself. This is a system-level approach, and has several advantages:
You are measuring the performance of client-browser too
You can see (to some extent) if the site performs better or worse in different browsers
It is compatible with techniques which do not lend themselves to "raw" web driver programs like ApacheBench
Of course it can take a large amount of work to create automated tests which are representative of real users actions.
Normally you'd have some special test-system with known hardware (ideally similar to production) and a database which includes certain objects which the test suite expects to find. You could also load a production-size (or bigger) simulated data set into this system.
If you used (for example) Selenium to automate functional tests, the functional tests could be reused to build a performance-test suite. That's what we did before.
what is the best tool (open or commercial) currently available, that lets me send customized requests to a web server and get back a response to check the performance?
i will be sending it a load of more than 20K per second, but i need to get numbers for each call made. also, the numbers might be in some microseconds or nanoseconds. How in this small measurement unit, can i work out a baseline and a benchmark?
If you're using Apache, Apache AB is a benchmarking to test how many requests your serve can serve per second and how well it handles load and concurrency. It's an open-source project - check it out here.
In addition, wikipedia has a nice list of benchmarking software for testing servers.
You can use the Web Application Stress Tool of Microsoft
The Microsoft WAS web stress tool is designed to realistically simulate multiple browsers requesting pages from a web site. You can use this tool to gather performance and stability information about your web application. This tool simulates a large number of requests with a relatively small number of client machines. The goal is to create an environment that is as close to production as possible so that you can find and eliminate problems in the web application prior to deployment.
You can find a list of Open Source software for performance (most of them are for web that send custom request to webserver).
Don't know if either of these have granularity better than milliseconds but check out JMeter (open source) and LoadRunner (Commercial). LoadRunner is not cheap but it allows you to span load generation across multiple machines with aggregated results.
