Prioritize visible content
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.
60.8KiB of the HTML response was required to render the above-the-fold content. This requires 3 network round-trips. However, if the HTML response were compressed, then the HTML required to render the above-the-fold content could be delivered in just 1 network round-trips. Enable compression for the HTML response in order to prioritize the visible content for this page.
Only about 68% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.
...
Minify HTML
Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 14.7KiB (25% reduction).
