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 25.4KiB (68% reduction).

Compressing http://graphviz.org/ could save 9.8KiB (68% reduction).
Compressing http://graphviz.org/modules/system/system.css?W could save 7KiB (71% reduction).
Compressing http://graphviz.org/themes/bluemarine/style.css?W could save 3.9KiB (70% reduction).
Compressing http://graphviz.org/sites/all/modules/ckeditor/ckeditor.css?W could save 1.8KiB (66% reduction).

Compressing http://graphviz.org/modules/system/system-menus.css?W could save 547B (62% reduction).

priority - 2Optimize images

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 19.6KiB (29% reduction).

Compressing http://graphviz.org/Gallery/directed/cluster.png could save 11.1KiB (29% reduction).
Compressing http://graphviz.org/app.png could save 7.5KiB (29% reduction).
Compressing http://graphviz.org/gvicons/doc-graphviz.png could save 1KiB (29% reduction).

priority - 2Prioritize 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.

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 46% of the final above-the-fold content could be rendered with the full HTML response.

priority - 1Reduce server response time

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 4.9KiB (28% reduction).

Minifying http://graphviz.org/modules/system/system.css?W could save 2.6KiB (28% reduction).
Minifying http://graphviz.org/themes/bluemarine/style.css?W could save 1.5KiB (28% reduction).
Minifying http://graphviz.org/sites/all/modules/ckeditor/ckeditor.css?W could save 750B (27% reduction).

graphviz.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.


graphviz.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.
