priority - 40Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 8 blocking script resources and 4 blocking CSS resources. This causes a delay in rendering your page.

Remove render-blocking JavaScript:

Optimize CSS Delivery of the following:

priority - 27Enable 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 267.7KiB (75% reduction).

priority - 16Prioritize 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.

137.7KiB 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 9% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.

priority - 4Minify 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 43.5KiB (32% reduction).

Minifying http://iucr.org/ could save 43.5KiB (32% reduction).

priority - 4Minify 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 33.8KiB (35% reduction).

priority - 1Minify 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 7.6KiB (32% reduction).

Minifying http://www.iucr.org/_designs/design-162/ourstyle.css could save 7.6KiB (32% reduction).

priority - 10Configure the viewport

Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.

priority - 3Size content to viewport

The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.

The page content is 984 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:

The element <a href="http://wdc.iucr.org/">World Directory</a> falls outside the viewport.
The element <input type="submit" name="submit" class="searchbutton"> falls outside the viewport.

priority - 2Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

The tap target <a href="http://it.iucr.org/">International Tables</a> and 1 others are close to other tap targets.

The tap target <input type="submit" name="submit" class="searchbutton"> is close to 1 other tap targets.

iucr.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.

iucr.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.
