Largest Contentful Paint
0.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
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.
Time to Interactive
0.4 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Server Backend Latencies
10 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.
First Contentful Paint
0.2 s
First Contentful Paint marks the time at which the first text or image is painted.
Speed Index
0.3 s
Speed Index shows how quickly the contents of a page are visibly populated.
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.
Avoids enormous network payloads
Total size was 136 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Minimizes main-thread work
0.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
