Eliminate render-blocking resources Potential savings of 450 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Web app manifest or service worker do not meet the installability requirements 1 reason
Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement
Avoid enormous network payloads Total size was 8,407 KiB
Large network payloads cost users real money and are highly correlated with long load times
Max Potential First Input Delay 220 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoid long main-thread tasks 1 long task found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Minimizes main-thread work 0.9 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Does not use HTTPS 143 insecure requests found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding [mixed content](https://developers.google.com/web/fundamentals/security/prevent-mixed-content/what-is-mixed-content), where some resources are loaded over HTTP despite the initial request being served over HTTPS. 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
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Keep request counts low and transfer sizes small 143 requests • 8,407 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Serve static assets with an efficient cache policy 142 resources found
A long cache lifetime can speed up repeat visits to your page
Speed Index 2.0 s
Speed Index shows how quickly the contents of a page are visibly populated
Serve images in next-gen formats Potential savings of 5,677 KiB
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
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
Time to Interactive 0.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive
First Contentful Paint 0.7 s
First Contentful Paint marks the time at which the first text or image is painted
Largest Contentful Paint 0.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Total Blocking Time 20 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Efficiently encode images Potential savings of 4,501 KiB
Optimized images load faster and consume less cellular data
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
Properly size images Potential savings of 6,906 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
JavaScript execution time 0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Avoid an excessive DOM size 1,058 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)
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
First CPU Idle 0.7 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/).
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 Meaningful Paint 0.7 s
First Meaningful Paint measures when the primary content of a page is visible
Avoid chaining critical requests 3 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
Reduce initial server response time Root document took 730 ms
Keep the server response time for the main document short because all other requests depend on it
