  In the history of web performance, “Load Time” was one of the first indicators used to measure the loading times of web pages. Over time, the other KPIs we’ve talked about—Speed Index, Time To Interactive, etc.—made their way onto the scene to assess the perception of speed and Load Time was retired to a dusty old shelf at the back of a storeroom. Let’s look back on this web performance metric that once played an important role, but which is no longer sufficient for assessing the speed of your website, and we’ll see why.

To assess your loading times and improve them, you need to precisely identify your tasks and events that take up the most time for browsers. But how do you know how long it takes a script to execute? Or when the main image on a page displays? What is the processing time for a user action before it executes? To answer all of these questions, the conventional tools and metrics may only provide limited responses. The answers can be found with custom metrics via the User Timing API. Jean-Pierre Vincent explains how to use it. Read More This article Custom Metrics: customize your web performance ..read more

The Time To First Byte (TTFB) expresses, in milliseconds, the time a server takes to respond. It is taken into account by Google and other search engines to assess the speed at which content will be available. So, as you’ve probably understood, it is an important indicator for your loading times, and also one that counts for your SEO.

A major challenge for technical teams: absorbing traffic spikes. To ensure the availability and continuity of your services, here are a few tips to get through traffic surges on your website. 1. Configure static resources cache The cache of static resources – such as images, JavaScripts, CSS – must be configured with the utmost care. By using a CDN, it is possible to force the cache on resources that can be cached for a pre-defined time. By doing so, it is no longer the server that serves and supports the load of requests for these resources, but the caches that are set up. Moreover, browsers ..read more

  Caching is one of the most effective techniques for having fast pages and for improving loading speeds by several hundred milliseconds. This time scale may seem minuscule, but cumulatively, all of those milliseconds can add up to seconds… and 1 extra second of loading time results in fewer conversions. It’s worth noting that in the retail sector, 1 extra second of loading time can make conversions fall by up to -20%. For a fast website, efficient cache management is crucial Each HTML page is made up of many files, like images, fonts, items coded in CSS or JavaScript, etc. Th ..read more
