Avoids enormous network payloads
Total size was 280 KiB
Large network payloads cost users real money and are highly correlated with long load times.
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.
Minimizes main-thread work
0.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
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.
JavaScript execution time
0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Initial server response time was short
Root document took 0 ms
Keep the server response time for the main document short because all other requests depend on it.
Time to Interactive
0.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Notes
* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.
** This was only counted from 11.Apr.2021.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
