Max Potential First Input Delay 210 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
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
Time to Interactive 1.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
First Contentful Paint 1.5 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid multiple page redirects Est savings of 230 ms
Redirects introduce additional delays before the page can be loaded
JavaScript execution time 0.6 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Render-blocking requests Est savings of 1,010 ms
Requests are blocking the page's initial render, which may delay LCP
Improve image delivery Est savings of 4 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP
Network Round Trip Times 30 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
Largest Contentful Paint 1.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Avoids enormous network payloads Total size was 701 KiB
Large network payloads cost users real money and are highly correlated with long load times
robots.txt is not valid 33 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
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
Server Backend Latencies 60 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
Initial server response time was short Root document took 0 ms
Keep the server response time for the main document short because all other requests depend on it
Speed Index 3.9 s
Speed Index shows how quickly the contents of a page are visibly populated
Legacy JavaScript Est savings of 38 KiB
Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile [Baseline](https://web.dev/articles/baseline-and-polyfills) features, unless you know you must support older browsers
Avoid long main-thread tasks 4 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Document request latency Est savings of 4 KiB
Your first network request is the most important
Reduce unused JavaScript Est savings of 244 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Mobile

Total Blocking Time 120 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Reduce unused JavaScript Est savings of 98 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
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
Speed Index 9.9 s
Speed Index shows how quickly the contents of a page are visibly populated
Cumulative Layout Shift 0.041
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoid multiple page redirects Est savings of 2,340 ms
Redirects introduce additional delays before the page can be loaded
Avoids enormous network payloads Total size was 477 KiB
Large network payloads cost users real money and are highly correlated with long load times
Largest Contentful Paint 6.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted
First Contentful Paint 4.6 s
First Contentful Paint marks the time at which the first text or image is painted
Server Backend Latencies 10 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
Max Potential First Input Delay 250 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task

Consider modifying your JavaScript build process to not transpile [Baseline](https://web.dev/articles/baseline-and-polyfills) features, unless you know you must support older browsers
Initial server response time was short Root document took 10 ms
Keep the server response time for the main document short because all other requests depend on it
Does not use HTTPS 1 insecure request 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
Time to Interactive 7.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
Network Round Trip Times 30 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
Render-blocking requests Est savings of 1,820 ms
Requests are blocking the page's initial render, which may delay LCP
Avoid large layout shifts 15 layout shifts found
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to [windowing](https://web.dev/articles/cls#what_is_cls)
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
Document request latency Est savings of 3,250 ms
Your first network request is the most important
Minimizes main-thread work 0.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
