Minimizes main-thread work 0.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Initial server response time was short Root document took 140 ms
Keep the server response time for the main document short because all other requests depend on it
Avoids enormous network payloads Total size was 243 KB
Large network payloads cost users real money and are highly correlated with long load times
Remove unused JavaScript Potential savings of 62 KB
Remove unused JavaScript to reduce bytes consumed by network activity
Largest Contentful Paint 0.5 s
Largest Contentful Paint marks the time at which the largest 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
Largest Contentful Paint element 1 element found
This is the element that was identified as the Largest Contentful Paint
JavaScript execution time 0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Preload key requests Potential savings of 260 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
First Meaningful Paint 0.4 s
First Meaningful Paint measures when the primary content of a page is visible
Time to Interactive 0.4 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Speed Index 0.7 s
Speed Index shows how quickly the contents of a page are visibly populated
Keep request counts low and transfer sizes small 19 requests • 243 KB
To set budgets for the quantity and size of page resources, add a budget.json file
Eliminate render-blocking resources Potential savings of 170 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
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 CPU Idle 0.4 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).
Includes front-end JavaScript libraries with known security vulnerabilities 2 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Uses efficient cache policy on static assets 7 resources found
A long cache lifetime can speed up repeat visits to your page
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
Avoid large layout shifts 1 element found
These DOM elements contribute most to the CLS of the page.
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Remove unused CSS Potential savings of 32 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
First Contentful Paint 0.4 s
First Contentful Paint marks the time at which the first text or image is painted
Minimize third-party usage Third-party code blocked the main thread for 0 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
Max Potential First Input Delay 40 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoids an excessive DOM size 208 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
