priority - 6Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

Remove render-blocking JavaScript:

http://static.parastorage.com/services/third-party…/2.1.15/require.min.js
http://static.parastorage.com/services/santa-versions/1.329.0/main-r.js

Optimize CSS Delivery of the following:

http://static.parastorage.com/services/santa-versions/1.329.0/viewer.css

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 (30% reduction).

Losslessly compressing http://static.wixstatic.com/media/7d739f_e5f440dc3…0.50_1.20_0.00_png_srz could save 10.2KiB (35% reduction).
Losslessly compressing http://static.wixstatic.com/media/7d739f_28bd000e8…0.50_1.20_0.00_png_srb could save 3.4KiB (24% reduction).
Losslessly compressing http://static.wixstatic.com/media/7d739f_de26fd715…0.50_1.20_0.00_jpg_srz could save 3.2KiB (53% reduction).
Losslessly compressing http://static.wixstatic.com/media/7d739f_93bb1ef9e…0.50_1.20_0.00_jpg_srz could save 2.8KiB (19% 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.

None of the final above-the-fold content could be rendered even with the full HTML response.

priority - 1Enable 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 10.4KiB (76% reduction).

Compressing http://www.kahoot.com/_api/dynamicmodel could save 10.4KiB (76% reduction).

priority - 0Minify 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 2.8KiB (21% reduction).

Minifying http://static.parastorage.com/services/santa-versions/1.329.0/main-r.js could save 2.8KiB (21% reduction) after compression.

priority - 0Leverage 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:

http://stats.g.doubleclick.net/dc.js (2 hours)

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 819B (39% reduction).

Minifying http://static.parastorage.com/services/santa-versions/1.329.0/viewer.css could save 819B (39% reduction) after compression.

kahoot.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.

kahoot.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.
