Eliminate render-blocking resources
Potential savings of 440 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
JavaScript execution time
0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Time to Interactive
0.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Uses efficient cache policy on static assets
6 resources found
A long cache lifetime can speed up repeat visits to your page.
Initial server response time was short
Root document took 440 ms
Keep the server response time for the main document short because all other requests depend on it.
Speed Index
0.8 s
Speed Index shows how quickly the contents of a page are visibly populated.
Avoids an excessive DOM size
210 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Contentful Paint
0.7 s
First Contentful Paint marks the time at which the first text or image is painted.
Notes
* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.
** This was only counted from 11.Apr.2021.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
