Desktop

Estimated Input Latency 10 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 4 KB

Minifying CSS files can reduce network payload sizes

Remove unused CSS Potential savings of 14 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

Server response times are low (TTFB) Root document took 580 ms

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

Eliminate render-blocking resources Potential savings of 100 ms

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

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

Total Blocking Time 20 ms

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

JavaScript execution time 0.2 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 4 KB

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

Speed Index 1.2 s

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

First CPU Idle 0.9 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 424 KB

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

Minimizes main-thread work 0.6 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

Avoid chaining critical requests 5 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

Avoids an excessive DOM size 272 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 7 KB

Minifying JavaScript files can reduce payload sizes and script parse time

First Meaningful Paint 0.6 s

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

Keep request counts low and transfer sizes small 36 requests • 424 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 21 resources found

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

Max Potential First Input Delay 70 ms

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

Time to Interactive 0.8 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

First Contentful Paint (3G) 2160 ms

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

Minify CSS Potential savings of 4 KB

Minifying CSS files can reduce network payload sizes

Tap targets are not sized appropriately 38% 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 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

Remove unused CSS Potential savings of 14 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
