All these images “is resized in HTML or CSS from 600×600 to 260×260. Serving a scaled image could save 45.4KiB (81% reduction).” are products from carrousel. I believe is part of Theme to regenerate all images for all sizes, is’nt it?
2. Leverage browser caching
We’ve already set the expires to htaccess, but still getting problems:
../themes/xstore/images/drag.png (expiration not specified)
../extensions/revolution.extension.actions.min.js (expiration not specified)
And there are another item, but is performing better than the previously
3. Optimize the order of styles and scripts
We’ve tried with “above the fold” plugin, but 8theme never provide us the Critical CSS, so when we activated these plugin, all the styles crash 🙁
