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.

49KiB 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 69% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.

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.

Leverage browser caching for the following cacheable resources:

priority - 32Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 6 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

Remove render-blocking JavaScript:

Optimize CSS Delivery of the following:

http://nationalacademies.org/site_assets/groups/na…et/na_dropdown_css.css

priority - 20Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

Enable compression for the following resources to reduce their transfer size by 191.9KiB (73% reduction).

priority - 8Prioritize 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.

49KiB 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 66% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.

priority - 2Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.

Minify JavaScript for the following resources to reduce their size by 19.5KiB (36% reduction).

priority - 1Minify 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 11.9KiB (25% reduction).

Minifying http://nationalacademies.org/ could save 11.9KiB (25% reduction).

priority - 0Minify CSS

Compacting CSS code can save many bytes of data and speed up download and parse times.

Minify CSS for the following resources to reduce their size by 4.8KiB (18% reduction).

nationalacademies.org Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

nationalacademies.org TRACEROUTE

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.
