Desktop

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

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

Speed Index 1.0 s

Speed Index shows how quickly the contents of a page are visibly populated

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).

Avoids enormous network payloads Total size was 1,339 KB

Large network payloads cost users real money and are highly correlated with long load times

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

First Contentful Paint 0.3 s

First Contentful Paint marks the time at which the first text or image is painted

Avoid chaining critical requests 7 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 902 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 Meaningful Paint 0.5 s

First Meaningful Paint measures when the primary content of a page is visible

Keep request counts low and transfer sizes small 45 requests • 1,339 KB

To set budgets for the quantity and size of page resources, add a budget.json file

Serve static assets with an efficient cache policy 4 resources found

A long cache lifetime can speed up repeat visits to your page

Max Potential First Input Delay 70 ms

The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task

Time to Interactive 0.7 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

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

User Timing marks and measures 6 user timings

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 930 ms

Time To First Byte identifies the time at which your server sends a response

Minimize third-party usage Third-party code blocked the main thread for 10 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 10 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

Mobile

First Contentful Paint (3G) 2344 ms

First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network

Estimated Input Latency 40 ms

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

Document uses legible font sizes 63.79% 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

User Timing marks and measures 6 user timings

Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences

Server response times are low (TTFB) Root document took 530 ms

Time To First Byte identifies the time at which your server sends a response

Reduce the impact of third-party code Third-party code blocked the main thread for 340 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 570 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

JavaScript execution time 0.7 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
