Optimizing your images and minifying your JavaScript and CSS files can help to that end.

Now that a large part of internet traffic comes from mobile users, and since 40 percent of mobile users give up on websites that take longer than 3 seconds to load, it's a good idea to keep your pages as small as possible. Page sizes tend to increase over the years, which can be a major problem for some users since large webpages take longer to load over mobile networks.

It refers to the number of kilobytes required to download all of a page's content.

Bytes inĪnother metric specific to WebPageTest, "bytes in" is just Google's fancy way of saying page size. Since the speed index is based on a percentage of the viewport, it's a useful metric to consider when optimizing your app for different screen sizes. Your speed index can tell you more about the user experience than TTFB since it measures how quickly the user actually sees content. WebPageTest calculates the speed index in milliseconds by capturing video of a webpage as it loads. Therefore, it is dependent on the viewport size. According to Google, speed index is the average amount of time it takes for all of the visual elements in the viewport to display. Since its introduction to back in 2012, the Google speed index has become a common standard for measuring web performance. If you're a WordPress user and want to easily reduce your TTFB, use a caching plugin such as Cache Enabler. Webpages and apps that rely heavily on databases typically have higher server times, which is why configuration optimization is so important. Since the base HTML file is always the first thing that users receive, TTFB is also a good indicator of your backend processing time. It's similar to time-to-first-byte, or TTFB, which is the amount of time it takes for the user to receive the first byte of data related to an HTTP request. Server time measures how long the server takes to respond to an initial request. Of course, it's up to developers to decide what's "meaningful." Take advantage of directives such as preload to improve the load times of critical assets. That's why we now also measure "the time to first meaningful paint," or the point when users actually see a meaningful image. The "first paint" metric tells us very limited information about how webpages load. Focusing on both of these metrics can simultaneously improve the user experience and your search engine rankings. Check out our complete guide on what's blocking the DOM? to learn how you can identify such bottlenecks. For instance, slow render times could be indicative of an issue with the JavaScript or CSS files in your render pipeline. TTFP is how long users have to wait until they see something besides a blank browser display.Ĭomparing your page load times to your render times can provide important insights. Perhaps a more meaningful metric to look at is time-to-first-paint, or TTFP. One benchmark to consider is the DOMContentLoaded event, which fires once the initial HTML document has been loaded and parsed. Render time may be defined in a couple of ways. This allows the important assets to load first and then start loading any third party scripts.

Consequently, it has become common practice to delay the loading of certain elements, such as advertisements and third party scripts, until after the onload event has executed. If it's more than this you should look into implementing web performance optimization techniques. Ideally, you'll want your page load time to be less than 2 seconds. Page load is usually defined as the amount of time it takes for the browser to fire the window.onload JavaScript event handler. Below are some of the most common indicators that developers look at when measuring web performance: Page load

Since there are dozens of metrics that relate to performance, you need to choose which ones are most relevant to your users. This guide will serve as an overview of the ways you should be measuring web performance as well as provide additional insight and tools to help improve your site's web performance. However, the process of measuring web performance can take many shapes and with all the web performance metrics available it can be confusing to know which ones you should be tracking.
