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
Avoids an excessive DOM size
230 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 CPU Idle
2.0 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/).
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport
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
Serve images in next-gen formats
Potential savings of 32 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
Uses efficient cache policy on static assets
11 resources found
A long cache lifetime can speed up repeat visits to your page
Largest Contentful Paint
0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Remove unused CSS
Potential savings of 23 KiB
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
Total Blocking Time
110 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted
Initial server response time was short
Root document took 470 ms
Keep the server response time for the main document short because all other requests depend on it
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
Speed Index
1.3 s
Speed Index shows how quickly the contents of a page are visibly populated
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
JavaScript execution time
0.8 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Minimizes main-thread work
1.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
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
Max Potential First Input Delay
150 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Keep request counts low and transfer sizes small
83 requests • 593 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Remove unused JavaScript
Potential savings of 77 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Minimize third-party usage
Third-party code blocked the main thread for 160 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
Time to Interactive
2.0 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Avoids enormous network payloads
Total size was 593 KiB
Large network payloads cost users real money and are highly correlated with long load times
Avoids large JavaScript libraries with smaller alternatives
0 large libraries found
Large JavaScript libraries can lead to poor performance. Prefer smaller, functionally equivalent libraries to reduce your bundle size
Eliminate render-blocking resources
Potential savings of 90 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Estimated Input Latency
20 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
Mobile
Keep request counts low and transfer sizes small
183 requests • 1,253 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
First Contentful Paint (3G)
3675 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network
Avoids enormous network payloads
Total size was 1,253 KiB
Large network payloads cost users real money and are highly correlated with long load times
Max Potential First Input Delay
800 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Defer offscreen images
Potential savings of 10 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Document uses legible font sizes
98.7% 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
Efficiently encode images
Potential savings of 8 KiB
Optimized images load faster and consume less cellular data
Minimize main-thread work
13.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Serve static assets with an efficient cache policy
37 resources found
A long cache lifetime can speed up repeat visits to your page
Total Blocking Time
4,460 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Largest Contentful Paint
2.9 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Avoids an excessive DOM size

Reduce JavaScript execution time
9.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
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
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
Eliminate render-blocking resources
