Desktop

Network Round Trip Times 0 ms

Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance

Avoid enormous network payloads Total size was 2,853 KiB

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

Avoid serving legacy JavaScript to modern browsers Potential savings of 7 KiB

Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers

Reduce unused JavaScript Potential savings of 224 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity

Avoid non-composited animations 14 animated elements found

Animations which are not composited can be janky and increase CLS

First Meaningful Paint 0.5 s

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

Serve images in next-gen formats Potential savings of 389 KiB

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

Speed Index 1.4 s

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

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

Minimize third-party usage Third-party code blocked the main thread for 70 ms

Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading

JavaScript execution time 0.9 s

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

First Contentful Paint 0.3 s

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

Largest Contentful Paint 1.5 s

Largest Contentful Paint marks the time at which the largest text or image is painted

Keep request counts low and transfer sizes small 121 requests • 2,853 KiB

To set budgets for the quantity and size of page resources, add a budget.json file

Cumulative Layout Shift 0.13

Cumulative Layout Shift measures the movement of visible elements within the viewport

Server Backend Latencies 0 ms

Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance

Time to Interactive 2.5 s

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

Properly size images Potential savings of 1,162 KiB

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

Serve static assets with an efficient cache policy 31 resources found

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

Avoid chaining critical requests 4 chains found

The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load

Max Potential First Input Delay 140 ms

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

Initial server response time was short Root document took 110 ms

Keep the server response time for the main document short because all other requests depend on it

User Timing marks and measures 8 user timings

Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences

Avoid long main-thread tasks 2 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

Total Blocking Time 50 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Minimizes main-thread work 1.9 s

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

Avoid large layout shifts 5 elements found

These DOM elements contribute most to the CLS of the page.

Avoid an excessive DOM size 1,094 elements

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)

Remove duplicate modules in JavaScript bundles Potential savings of 13 KiB

Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Mobile

Avoid long main-thread tasks 15 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

Avoids enormous network payloads Total size was 2,167 KiB

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

Avoid large layout shifts 5 elements found

These DOM elements contribute most to the CLS of the page.

Server Backend Latencies 0 ms

Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance

Avoid serving legacy JavaScript to modern browsers Potential savings of 7 KiB

Properly size images Potential savings of 554 KiB

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

Defer offscreen images Potential savings of 640 KiB

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

Keep request counts low and transfer sizes small 63 requests • 2,167 KiB

To set budgets for the quantity and size of page resources, add a budget.json file

Initial server response time was short Root document took 310 ms

Keep the server response time for the main document short because all other requests depend on it

Reduce unused JavaScript Potential savings of 209 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity

Reduce JavaScript execution time 1.9 s

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

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

Cumulative Layout Shift 0.118

Cumulative Layout Shift measures the movement of visible elements within the viewport

Reduce the impact of third-party code Third-party code blocked the main thread for 350 ms

Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading

Time to Interactive 12.6 s

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

Serve images in next-gen formats Potential savings of 254 KiB

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

Document uses legible font sizes 100% legible text

Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px

First Contentful Paint 1.1 s

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

Total Blocking Time 340 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Avoid an excessive DOM size 1,089 elements

First Meaningful Paint 1.1 s

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

Speed Index 4.8 s

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

Avoid chaining critical requests 4 chains found

Network Round Trip Times 0 ms

Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance

Largest Contentful Paint 8.5 s

Largest Contentful Paint marks the time at which the largest text or image is painted

Serve static assets with an efficient cache policy 24 resources found

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

First Contentful Paint (3G) 1958 ms

First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network

Minimize main-thread work 3.4 s

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

Max Potential First Input Delay 260 ms

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

Tap targets are not sized appropriately 92% appropriately sized tap targets

Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements
