Fonxe Traffic, Page Speed and Technology Analysis

A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

A long cache lifetime can speed up repeat visits to your page.

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.

Speed Index shows how quickly the contents of a page are visibly populated.

Consider using `` to prioritize fetching resources that are currently requested later in page load.

First Contentful Paint marks the time at which the first text or image is painted.

First Meaningful Paint measures when the primary content of a page is visible.

Serve images that are appropriately-sized to save cellular data and improve load time.

Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.

Optimized images load faster and consume less cellular data.

Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.

Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity.

First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input.

Large network payloads cost users real money and are highly correlated with long load times.

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.

Minifying JavaScript files can reduce payload sizes and script parse time.
