Total Blocking Time 70 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Minimizes main-thread work 1.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
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
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
Max Potential First Input Delay 90 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoids enormous network payloads Total size was 652 KiB
Large network payloads cost users real money and are highly correlated with long load times
Legacy JavaScript Est savings of 14 KiB
Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile [Baseline](https://web.dev/articles/baseline-and-polyfills) features, unless you know you must support older browsers
Use efficient cache lifetimes Est savings of 74 KiB
A long cache lifetime can speed up repeat visits to your page
Initial server response time was short Root document took 10 ms
Keep the server response time for the main document short because all other requests depend on it
JavaScript execution time 0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Largest Contentful Paint 0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted
robots.txt is not valid 1 error found
If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed
Time to Interactive 0.9 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
Reduce unused CSS Est savings of 35 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease 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
Links do not have descriptive text 20 links found
Descriptive link text helps search engines understand your content
Reduce unused JavaScript Est savings of 52 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
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
