It has also won several awards. More importantly, it has a pretty attractive pricing and licensing model. WebLOAD has an extensive range of features and supports multiple web technologies, allowing you to perform load testing and mimic massive user loads. You can quickly build tests, generate load and analyze the results with a rich set of reports that identifies specific performance issues.
The load scenario is generated in JavaScript so that you can make enhancements as per your requirements. The standard language is enhanced with inbuilt load-testing methods and objects that offer HTTP functionality, DOM functionality, load methods and more.
The tool also includes automated correlation to find and replace session IDs, time and other dynamic values. An open-source load testing tool, Apache JMeter is also built on a Java platform.
Although it is considered mainly as a web performance testing tool, you can also integrate it with the test plan. You can create a load test and functional test plans as well. The tool can be loaded into a network or server in order to assess its performance under various working conditions. Apache JMeter was first introduced for web application testing , but today it is used for a number of other purposes as well. It is particularly useful to test the performance of Java objects, Perl Scripts and Servlets, and other resources.
The tool can also test the performance of static resources, Web dynamic languages like ASP. It can simulate a heavy load on server groups, individual servers, objects or networks to assess its strength and performance under different types of loads.
A key advantage of this tool is that it can handle and generate thousands of users simultaneously. It enables you to gather all performance-related and infrastructure-based information. It works by creating a scenario that contains the script that is to be executed.
The number of virtual users needed is also generated, along with other prerequisites for running the test and generating the expected results. The number of virtual users to be generated could range from a few hundred to a few thousand. The scenario could be manual or goal-oriented, in which the tool automatically generates the scenarios based on previously specified goals by the tester.
The series of actions to be performed are recorded onto the virtual user script. A load generator is then used to run the users, generating the necessary level of load on the system. The processes to be measured are represented as transactions. Once the load is generated, the system behavior is monitored and analyzed. The Rational Performance Tester from IBM is an automated web performance testing tool for web and server-based applications in which there is an input and output process.
The tool generates a demo of the original transaction process, gathering and analyzing statistical information to increase efficiency. Any server or website leakage can be immediately identified and rectified, and it can be used to create an error-free, effective cloud computing service.
The tool can identify the presence and root cause of bottlenecks in system performance. It combines several ease-of-use features along with detailed analysis, simplifying test creation, lead generation, and data collection processes to ensure that their web applications can accommodate the required user loads. It can also be used to analyze further steps to be taken based on the performance of the website and end result of the tests. This, in turn, helps improve and optimize the performance of your web application.
The tool works by increasing the traffic on your website and then analyzing the performance of the application under heavy load. You get to understand the capacity of the application and how many users it can handle simultaneously. It simulates user activity in web and mobile applications as well, and monitors the infrastructure behavior. You can choose from cloud-based load generators for the performance test.

Wondering why your page is slow? We'll breakdown your page performance in a summarized report. Track your performance over time We'll test your page on a schedule and keep track of how it's doing.
Learn why monitoring is important. Get notified when your page is slow Set up an alert and get notified when your page underperforms. See how your page loads on different devices Test your page on a real Android device or on over 30 different Simulated Device options. This could be Javascript, CSS, or any other type of code that might block the rendering of the current webpage.
For Javascript, we can run a little script that will defer the scripts that would otherwise block the rendering of our pages. The next part to tackle is CSS. With your CSS the goal is to get it as small as possible and there are two ways to do it, one would be to remove all the unnecessary classes and either remove them altogether or move them to a different CSS file that can be loaded on other pages or after the critical content of the page has loaded.
The second thing you could do is minify your CSS file. This is a process where you take the unnecessary characters from your files that would otherwise take up space thus taking longer to load.
Most often then not developers use a piece of software to get this done. The next thing to look for is your HTTP requests. Every time you load a website, there are a series of requests being made to the servers. Every request will have a response and each server will have a set number of concurrent requests it can handle.
The more requests you have, the more requests your server will have to deal with, and the longer it will take to respond. These requests can be hard to track and most often than not the number of requests fluctuates up and down especially if you are working with any third party services.
With a simple setup, you can track the overall number of requests, load time, responses, and much more. The reason why you are here in the first place, the top website speed testing tools you can use right now. Now that you got the basics of website speed testing, here are some of the best tools to help you test page load and improve website performance.
While still being new to the Sematext Suite, Synthetics is a synthetic monitoring tool that has quickly become a favorite amongst our users. Getting started is really easy and only takes a couple of minutes before you start to actually monitor your resources with the help of the intuitive UI.
Sematext Synthetics comes with a day trial. For years Google PageSpeed Insights has been the go-to tool for testing and grading your website. The higher the number, the faster the website is. While many other tools in this list allow you to customize requests, set up alerts, and select different locations to run your tests, Google PageSpeed Insights will not give you those options. Uptrends offers a straightforward test from one of 10 locations and you can configure the test to run either from a mobile device or a desktop.
For the desktop test, you can also pick the resolution of the screen one of four browsers Chrome, Firefox, PhantomJS, and IE and bandwidth throttling to test the site under different speed scenarios. You can also choose to simulate your tests over a slow mobile network or a fast 4G network.
The result will be graded from F to A and will include information on compression, TTFB, caching, waterfall charts for the resources load speed, and more. It also features a rather special test where they run a test 3 times and displays all three data sets. GTmetrix allows you to get detailed information on your page speed, timings, performance score, and much more.
