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
Server response times are low (TTFB) Root document took 320 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources Potential savings of 70 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
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 0.4 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 0.3 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 20 KB
Large network payloads cost users real money and are highly correlated with long load times
Minimizes main-thread work 0.0 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 2 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
Avoids an excessive DOM size 30 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 0.3 s
First Meaningful Paint measures when the primary content of a page is visible
Keep request counts low and transfer sizes small 4 requests • 20 KB
To set budgets for the quantity and size of page resources, add a budget.json file
Uses efficient cache policy on static assets 1 resource found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay 20 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive 0.3 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

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 Contentful Paint (3G) 2490 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 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
Server response times are low (TTFB) Root document took 150 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources Potential savings of 180 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
