Desktop

Reduce the impact of third-party code Third-party code blocked the main thread for 430 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 240 ms

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

Reduce JavaScript execution time 2.5 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 164 KB

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

Properly size images Potential savings of 33 KB

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

Speed Index 3.0 s

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

First CPU Idle 2.4 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).

Avoid enormous network payloads Total size was 3,512 KB

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

Minimize main-thread work 4.2 s

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

robots.txt is not valid 22 errors found

If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed

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 10 vulnerabilities detected

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

Avoid chaining critical requests 10 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 2,238 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 19 KB

Minifying JavaScript files can reduce payload sizes and script parse time

First Meaningful Paint 1.3 s

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

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

Serve static assets with an efficient cache policy 90 resources found

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

Max Potential First Input Delay 200 ms

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

Time to Interactive 3.8 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 28.8 s

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

Estimated Input Latency 30 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 21 KB

Minifying CSS files can reduce network payload sizes

Remove unused CSS Potential savings of 149 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

Serve images in next-gen formats Potential savings of 145 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

User Timing marks and measures 76 user timings

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

Reduce server response times (TTFB) Root document took 600 ms

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

Eliminate render-blocking resources Potential savings of 170 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 14 KB

Optimized images load faster and consume less cellular data

Enable text compression Potential savings of 298 KB

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

Mobile

Uses deprecated APIs 1 warning found

Deprecated APIs will eventually be removed from the browser

Serve images in next-gen formats Potential savings of 466 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

Avoid multiple page redirects Potential savings of 780 ms

Redirects introduce additional delays before the page can be loaded

User Timing marks and measures 85 user timings

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

Server response times are low (TTFB) Root document took 80 ms

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

Eliminate render-blocking resources Potential savings of 1,420 ms
