Avoid chaining critical requests 14 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 816 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 152 KB

Minifying JavaScript files can reduce payload sizes and script parse time

First Meaningful Paint 0.9 s

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

Keep request counts low and transfer sizes small 199 requests • 4,275 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 48 resources found

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

Max Potential First Input Delay 110 ms

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

Time to Interactive 4.2 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 20.3 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 3 KB

Minifying CSS files can reduce network payload sizes

Remove unused CSS Potential savings of 574 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 274 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

Does not use HTTPS 1 insecure request found

All sites should be protected with HTTPS, even ones that don't handle sensitive data. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs

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

Reduce server response times (TTFB) Root document took 1,170 ms

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

Eliminate render-blocking resources Potential savings of 360 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 141 KB

Optimized images load faster and consume less cellular data

Enable text compression Potential savings of 21 KB

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

Minimize third-party usage Third-party code blocked the main thread for 150 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 130 ms

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

JavaScript execution time 1.3 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 495 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 1,479 KB

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

Speed Index 2.6 s

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

First CPU Idle 2.7 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 4,100 KB

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

Minimize main-thread work 2.6 s

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

First Contentful Paint 0.8 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 5 vulnerabilities detected

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

Mobile

Minify CSS Potential savings of 3 KB

Minifying CSS files can reduce network payload sizes

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 99.49% 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 574 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 211 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

Server response times are low (TTFB) Root document took 310 ms

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

Eliminate render-blocking resources Potential savings of 1,400 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 104 KB

Optimized images load faster and consume less cellular data

Reduce the impact of third-party code Third-party code blocked the main thread for 2,240 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 1,880 ms

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

Reduce JavaScript execution time 6.7 s

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

Defer offscreen images Potential savings of 431 KB

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

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

Properly size images Potential savings of 290 KB

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

Speed Index 8.1 s

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