Desktop

Reduce server response times (TTFB) Root document took 1,370 ms

Time To First Byte identifies the time at which your server sends a response

Eliminate render-blocking resources Potential savings of 1,410 ms

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

Efficiently encode images Potential savings of 40 KB

Optimized images load faster and consume less cellular data

Enable text compression Potential savings of 7 KB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes

Reduce the impact of third-party code Third-party code blocked the main thread for 560 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

Total Blocking Time 960 ms

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

Reduce JavaScript execution time 2.8 s

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

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

Defer offscreen images Potential savings of 242 KB

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

Speed Index 3.7 s

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

First CPU Idle 3.0 s

First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input. [Learn more](https://web.dev/first-cpu-idle).

Avoids enormous network payloads Total size was 1,973 KB

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

Minimize main-thread work 4.9 s

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

First Contentful Paint 1.2 s

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

Includes front-end JavaScript libraries with known security vulnerabilities 9 vulnerabilities detected

Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers

Avoid chaining critical requests 40 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

Avoid an excessive DOM size 2,241 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)

Minify JavaScript Potential savings of 18 KB

Minifying JavaScript files can reduce payload sizes and script parse time

First Meaningful Paint 1.2 s

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

Keep request counts low and transfer sizes small 338 requests • 1,973 KB

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

Serve static assets with an efficient cache policy 172 resources found

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

Max Potential First Input Delay 490 ms

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

Time to Interactive 6.4 s

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

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

Page load is not fast enough on mobile networks Interactive on simulated mobile network at 24.5 s

A fast page load over a cellular network ensures a good mobile user experience

Estimated Input Latency 110 ms

Estimated Input Latency is an estimate of how long your app takes to respond to user input, in milliseconds, during the busiest 5s window of page load. If your latency is higher than 50 ms, users may perceive your app as laggy

Minify CSS Potential savings of 2 KB

Minifying CSS files can reduce network payload sizes

Remove unused CSS Potential savings of 41 KB

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

Uses deprecated APIs 1 warning found

Deprecated APIs will eventually be removed from the browser

Serve images in next-gen formats Potential savings of 378 KB

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

Mobile

Speed Index 10.7 s

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

Estimated Input Latency 1,080 ms

Tap targets are sized appropriately 100% 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

Document uses legible font sizes 92.59% 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
