Ratta Traffic, Page Speed and Technology Analysis

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

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

Time to interactive is the amount of time it takes for the page to become fully interactive.

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

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

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

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

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.

The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task.

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).

Optimized images load faster and consume less cellular data.

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

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

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

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.
