Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 1 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Optimize CSS Delivery of the following:
https://umbraco.com/dist/css/master.min.css?v=637115829762421870
Prioritize 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 68% of the final above-the-fold content could be rendered with the full HTML response.
...
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 55.3KiB (11% reduction).
Compressing https://umbraco.com/media/6320/anders-frontpage.png could save 42.2KiB (11% reduction).
...
Leverage browser caching
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:
https://js.intercomcdn.com/shim.latest.js (5 minutes)
...
Reduce server response time
In our test, your server responded in 0.34 seconds.
There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.
Enable 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 1,023B (52% reduction).
Compressing https://umbraco.com/dist/illustrations/bg_globe.svg could save 1,023B (52% reduction).
