Liquid Web has developed a Hosting Toolkit that provides web developers and curious technophiles a Performance Tool for website testing. We make it easier than ever to optimize and troubleshoot by providing connectivity tests from different geographical locations accompanied with an easy to read grading system for site performance.


How Do I Test My Site?

Getting started with a performance test is a straightforward process. Type in any domain and select Start Test for a performance report that is rich in detail.

You can choose to leave your testing location as default or switch it up!
Changing Location: Allows you the choice to test connectivity from our data centers in Lansing, MI or Amsterdam, NL.

Browser Choice:  View your website from Chrome to troubleshoot browser specific site issues.


How Do I Optimize My Website?

After the test is performed you’ll see how well the site performed based on its letter grade in each category.  If you scored low in some areas, click on the letter grade to find detailed notes on how to improve. As a bonus, this section has useful links to our Knowledge Base which houses tons of easy to follow tutorials for improving website performance.

The letter rating system is broken down into specific categories:

  • TTFB (Time to First Byte) –  the duration from the user’s HTTP request to the first byte of data is received by the end user.
  • Keep-Alive Enabled – a header setting in Apache that allows for a persistent connection from a client to the server.
  • Compressed Files – are scripts that have been reduced in size for faster transmission rates.
  • Compressed Images – much like compressed files, an image’s code can also be reduced for enhancing delivery speeds.
  • Cache static content – static content includes anything on a website that does not change like images, CSS or Javascript files.  Caching static content means you’ll store a copy of the file while indicating the length of cache time for certain types of files.
  • Effective use of CDN – CDN’s keep a copy of your website and delivers it globally based on geographical efficiency, thus reducing travel time and increasing speed.


Choose Your View

There are a few other options to consider when optimizing or troubleshooting your site. Below the letter grade you find a grey bar that includes a bit more gradual insight.

  • Summary – This view provides us with a combination of the options discussed below.   It is ideal to reduce the number of requests and the waterfall chart is an extremely helpful visual for detecting bottlenecks as it shows each process your page goes through to complete the rendering.
  • Details – Shows a waterfall of each call your website performs, measured in milliseconds. A color-coded segmentation of the different types of requests is based on the color chart above the waterfall.
  • Performance Review – Provides a visual checklist of the calls made that produced the letter grade at the top of the page. This performance view can also be accessed by clicking on the letter grade.  Scroll further down the page to see a detailed breakdown of each criterion.
  • Content Breakdown – The pie charts let us know the percentages of requests which is nestled alongside another pie chart that marks the MIME types size of each.
  • Domains- Indicates the number of connections to 3rd party domains like Facebook. This gives insight into which domains your site pulls content from and can be an excellent tool to find a SPOF (single point of failure).
  • Processing Breakdown – Displays a detailed view of Java’s main thread including two subsections of categories and events organized by milliseconds.  The processing breakdown is useful in determining what could be blocking or slowing down Java’s main thread.
  • Screen Shot- Take a look at the site being tested via a screenshot or even download a video of the site rendering.  These screenshots are useful to view if the site looks different from your browser.


Our Performance Tool has almost unlimited viewing options and truly is a developer’s best friend for testing the performance of any website.  Since it is such a robust tool, additional documentation is provided in the Documentation tab located on the top of the screen or by following this link.
