Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.

Enable text compression. Potential savings of 1,067 KiB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Properly size images. Potential savings of 770 KiB

Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.

Efficiently encode images. Potential savings of 559 KiB
