Keep request counts low and transfer sizes small 80 requests • 5,256 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 38 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay 100 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive 2.2 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 10.5 s
A fast page load over a cellular network ensures a good mobile user experience
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 36 KB
Minifying CSS files can reduce network payload sizes
Remove unused CSS Potential savings of 204 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 3,072 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 51 insecure requests 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 7 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 460 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources Potential savings of 1,030 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 911 KB
Optimized images load faster and consume less cellular data
Enable text compression Potential savings of 2 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 10 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 30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
JavaScript execution time 0.4 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 605 KB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Speed Index 2.0 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 1.8 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 5,256 KB
Large network payloads cost users real money and are highly correlated with long load times
Minimizes main-thread work 1.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
First Contentful Paint 1.3 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 4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Avoid chaining critical requests 24 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 954 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)
First Meaningful Paint 1.6 s
First Meaningful Paint measures when the primary content of a page is visible

Tap targets are not sized appropriately 54% 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 84.18% legible text
