priority - 10Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 7 blocking script resources and 4 blocking CSS resources. This causes a delay in rendering your page.

Remove render-blocking JavaScript:

https://platform.linkedin.com/in.js
https://cdnjs.cloudflare.com/ajax/libs/jquery/1.11.1/jquery.min.js
https://cdnjs.cloudflare.com/ajax/libs/twitter-boo….0/js/bootstrap.min.js

https://cdnjs.cloudflare.com/ajax/libs/moment.js/2…ment-with-langs.min.js

Use asynchronous versions of the following scripts:

priority - 4Optimize images

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

Optimize the following images to reduce their size by 34.5KiB (37% reduction).

Compressing https://blog.miguelgrinberg.com/static/miguel.jpg could save 17.2KiB (89% reduction).
Compressing https://blog.miguelgrinberg.com/static/images/pycon2016.png could save 9.8KiB (22% reduction).
Compressing https://blog.miguelgrinberg.com/static/flask-book-cover-tiny.png could save 5KiB (19% reduction).
Compressing https://blog.miguelgrinberg.com/static/rss-small.png could save 2.6KiB (73% 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 47% of the final above-the-fold content could be rendered with the full HTML response.

miguelgrinberg.com 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.

miguelgrinberg.com 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.
