Avoid slowing down the critical rendering path (fastRender)Maybe you could server push your CSS resources for faster rendering but that is actually really hard to get right :(. The style https://strawdogs.co/css/main.css is larger than the magic number TCP window size 14.5 kB. Make the file smaller and the page will render faster. The style https://strawdogs.co/lib/font-awesome/css/all.min.css is larger than the magic number TCP window size 14.5 kB. Make the file smaller and the page will render faster. The page has 2 render blocking CSS request(s) and 0 blocking JavaScript request(s) inside of head.90
