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.180.8KiB of the HTML response was required to render the above-the-fold content. This requires 4 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 2 network round-trips. Enable compression for the HTML response in order to prioritize the visible content for this page.
Only about 8% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.
