Desktop
Serve static assets with an efficient cache policy
157 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay
80 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive
4.2 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 26.3 s
A fast page load over a cellular network ensures a good mobile user experience
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
Remove unused CSS
Potential savings of 105 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 7,468 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
156 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
1 user timing
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
Reduce server response times (TTFB)
Root document took 2,300 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources
Potential savings of 460 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Enable text compression
Potential savings of 166 KB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes
Efficiently encode images
Potential savings of 585 KB
Optimized images load faster and consume less cellular data
Minimize third-party usage
Third-party code blocked the main thread for 20 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
60 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
JavaScript execution time
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
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 1,219 KB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Properly size images
Potential savings of 1,258 KB
Serve images that are appropriately-sized to save cellular data and improve load time
Speed Index
6.0 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle
3.0 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).
Avoid enormous network payloads
Total size was 10,209 KB
Large network payloads cost users real money and are highly correlated with long load times
Minimize main-thread work
2.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
First Contentful Paint
0.8 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
7 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Avoid chaining critical requests
10 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
2,936 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)
Minify JavaScript
Potential savings of 8 KB
Minifying JavaScript files can reduce payload sizes and script parse time
First Meaningful Paint
0.8 s
First Meaningful Paint measures when the primary content of a page is visible
Keep request counts low and transfer sizes small
273 requests • 10,209 KB
To set budgets for the quantity and size of page resources, add a budget.json file
