This free online website speed-testing tool by Pingdom (a server, network and website monitoring service) provides you with several reports such as a breakdown of how long each web page object (e.g. images, style sheets and JavaScript libraries) takes to download and performance grades for things like browser caching. Another useful report is a page analysis that provides information on load time, page size and requests.
This free website speed and performance testing tool by BrowserMob, a company that offers website load testing and monitoring service, gives you a ton of information about your web page speed such as average load time, total page weight and number of page objects. It pings your web page from four locations so that you can get a global view of your website’s performance.
This interesting tool pits two websites against each other in terms of loading time; for example, you can find out if Google loads faster than Bing does by using this tool. This can be a simple tool for comparing whether your website performs better or worse than competing sites. This open source tool (
view the source on GitHub) was originally created to promote the importance of web performance.
This nifty online tool tests your web page’s rendering speed in real browsers (Chrome, Firefox and IE) and gives you a choice of conducting the test from several locations around the world. It also has advanced settings with options for simulating common Internet connection speeds (e.g. DSL and 56K dial up) and ad-blocking so you can see the performance cost of running ads on your site.
This simple web page speed test analyzer — probably one of the oldest tools out there with its first version released in 2003 — gives you data on your web page’s size, assets and load time. It also supplies you with recommendations on things you can make better.
This is the web-based version of the open source server application by the same name (
Show Slow). Show Slow allows you to add a URL to be monitored (publicly) and regularly captures results from three popular testing tools: YSlow, Page Speed and dynaTrace. This tool requires registration.
This web-based website speed testing tool displays relevant data on page-rendering time, such as total download time, number of connections made and number of requests made. It also has some bonus features such as being able to run the test even if the web page has HTTP authentication (simply supply it with the password to the page) and the ability to simulate different types of Internet connections.
Load Impact’s free online load testing and performance tool gives you plenty of data on your
website’s ability to handle website traffic. This online web performance evaluation tool has the ability to show graphed data such as user load time (simulated by an automated virtual machine) and requests per second (helpful for seeing how durable your web server is and how fast it can handle web page requests).
OctaGate SiteTimer is a rather straightforward online tool: you plug in the URL you want to test and, in turn, it will output a bar graph featuring all web page objects containing information such as download start times, end times and duration for each. This tool is beneficial for quickly discovering slow-loading page objects so that you can
optimize them to improve website speed.
