Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Your page has 10 blocking script resources and 6 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by https://developers.google.com/speed/docs/insights/OptimizeImages (636.8KiB reduction).
Compressing https://i.pximg.net/img-master/img/2013/04/25/18/54/59/35231457_p0_master1200.jpg could save 635.2KiB (78% reduction).
Compressing https://s.pximg.net/www/images/beta/pixiv_logo.png could save 1.6KiB (36% reduction).
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 5% of the final above-the-fold content could be rendered with the full HTML response.
