Opportunities
Initial server response time was short
Root document took 30 ms

Potential savings of 679 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
First Meaningful Paint
1.5 s
First Meaningful Paint measures when the primary content of a page is visible.
Speed Index
1.5 s
