There are many performance rules out there, but ultimately, load time is the only performance metric that matters. How fast is fast enough for a web application? Here's a quick overview of key performance metrics :. Because of this, the importance of performance is increasing, and engineering teams need to treat performance as a feature. The goal of a performance load test is to understand how your applications behave under heavy load conditions.
To get started, you need to understand the baseline performance of your application and know that the performance of each transaction is unique.
For example, in an e-commerce application, a home page transaction is likely highly cached and very fast, whereas a checkout transaction is more complicated and must talk to a payment service, shipping service, etc. To ensure that users have a great experience, you must test the most common flows for your users and understand performance both in the browser and on the server.
But before jumping into load-testing tools, don't make the mistake of overlooking how your application performs with just one user. Believe it or not, most folks skip the most obvious place to start with performance—verifying that their application can perform well for one user before even starting concurrent load or stress testing. James Pulley , practice manager of performance engineering and test at TEKsystems Global Services and a podcaster at PerfBytes , reminded me in our last TestGuild performance podcast that most engineers focus only on how their applications perform for many concurrent users.
How many, though, can answer whether the app scales for only one person? You have to ask that question before even thinking about a load test. Most modern applications spend more time in the browser than on the server side.
These feature-rich front ends add a new layer that needs to be measured. So measuring the rendering time of an application that is under test on a client's local machine becomes critical.
This open-source tool analyzes your website's speed and performance based on performance best practices and timing metrics. You can analyze one site, analyze and compare multiple sites, or let your continuous integration server break your build when you have exceeded your performance budget. It is not always possible for teams to modify the applications to optimize client-side performance. When getting started with performance testing, don't overlook another asset your software team probably already has—a functional testing script.
Some open-source functional test tools can be leveraged to gather some high-level performance info that should help your team. Once you have a good understanding of your client-side front-end performance, it's time to move on to some server-side load testing tools. Apache Bench and Siege are great for quick load tests from a single endpoint. If you just need to get a sense of the requests per second for an endpoint, these are great solutions.
A more advanced approach—and my personal preference—is Locust. I've included it in the list below, along with a few other tools to consider. While you have many open-source tools from which to choose for performance management, it's not always wise to build and manage your own performance testing tools and infrastructure. You may determine that it's not worth the engineering resources required to load test when you can pay for a proven commercial product or service.
Such tools let you more easily build, execute, and analyze performance tests, but you have to have the budget pay for it. Should you go with open source, or will a commercial tool provide more value? From the tons of comments on your articles, I guess I am not the only one having all the enjoyment here!
Keep up the good work. Did you know that PushtoTest is now Appvance? Check it out! I want to test a. I have to test with vusers It works even if you have your own JMeter script, just upload it and it runs from different locations. NeoLoad Free Edition allows to test up to 50 vusers and monitor the app servers.
I find it useful for Mobile apps testing. Hello everybody!! Thank you in advance and good day. Try loadfocus. Can anyone tell me a single page applications load testing tool which supports https and JavaScript. Need to have it for client side app testing. Post a Comment. About The Author. NET Controls. Follow him on twitter suprotimagarwal. It can be load the network or server which is used to evaluate the performance and compute its operation under various scenarios.
It is implemented to test the web applications but now its scope is extended for many purposes. It is implemented by Micro Focus and also used as a tool for performance testing. It is also used for computing and analyzing the results and performance of the system when it is prone to actual load. It can be used by multiple users simultaneously. It is comprised of a controller, virtual user generator and load generator.
It is designed by HP and used to do stress testing and the outcome is generated by Loadrunner and it is measured as standards. It is available as a free and open source. It is based on Java and insisted to perform all types of stress and load testing. The performance and load testing make advanced testing functions by use of JMeter. It is used to conduct stress testing on all web-based applications and other mobile applications.
It has several merits and it can be implemented in all types of servers and also executes stress testing on business intelligence applications, ERP and CRM, etc. This is a guide to Stress Testing Tools. Here we also discuss the Introduction and top stress testing tools which include webload, loadninja, and smartmeter, etc. You may also have a look at the following articles to learn more —.
