Speed Index6955target < 4500 ms
Speed Index is a page load performance metric that shows you how quickly the contents of a page are visibly populated. The lower the score, the better. Source: Lighthouse - Learn more

These metrics are collected from the initial request until the browser considers the page loaded (JavaScript onLoad event). This usually happens after all of the image content has loaded but may not include content that is triggered by javascript execution.

Speed
Load time21200 ms
Also known as the document complete time, it’s the time from the initial request until the browser load event. It can vary based on server location, device, browser, and third-party apps. Source: WebPagetest - Learn more
Page load is fast enough on 3G
A fast page load over a 3G network ensures a good mobile user experience. Source: Lighthouse - Learn more
First byte1874 ms
The time from the initial request to the first byte of the response. Source: WebPagetest - Learn more
First Contentful Paint ms
First contentful paint marks the time at which the first text/image is painted. Source: Lighthouse - Learn more
First meaningful paint6060 ms
First meaningful paint measures when the primary content of a page is visible. It's essentially the paint after which the biggest above-the-fold layout change has happened, and web fonts have loaded. Source: Lighthouse - Learn more
Estimated Input Latency18 ms (target < 50 ms)
The score above is an estimate of how long your app takes to respond to user input, in milliseconds. There is a 90% probability that a user encounters this amount of latency, or less. 10% of the time a user can expect additional latency. If your score is higher than Lighthouse's target score (< 50ms), users may perceive your app as laggy. Source: Lighthouse - Learn more
Uses persistent connections (keep alive)Score: 100%
Closing connections are a missed opportunity for performance enhancement: additional round-trips between the user and the server to initiate a connection is redundant and time-consuming. Keep-Alive measures the effectiveness of connection reuse. The purpose of this grade is to evaluate the extent to which requests are inefficiently reopening connections. Source: WebPagetest - Learn more
First CPU Idle9195 ms
First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input. Source: Lighthouse - Learn more
Time to Interactive19854 ms
Interactive marks the time at which the page is fully interactive. Source: Lighthouse - Learn more
Page weight
Uses compression (gzip, zopfli, deflate, brotli)Score: 100%
This rule triggers when detecting that compressible resources were served without gzip compression. Source: WebPagetest - Learn more
Uses a CDN for all static assetsScore: 34%
Each request for a piece of content to the web server has to travel from the user's browser all the way to the server and back. A content delivery network (CDN) is a system for distributing resources to servers geographically closer to users. The main benefit of this is that the round-trip time is faster. The passing grade for using a CDN effectively is to have at least 80% of static resources served from a CDN. Source: WebPagetest - Learn more
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. Source: PageSpeed Insights - Learn more

Minify CSS
Minification refers to the process of removing unnecessary or redundant data in order to reduce file size without affecting how the resource is processed by the browser - e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on.

Avoids an excessive DOM size932 nodes
Number of elements in the document. Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows. Source: Lighthouse - Learn more

Compressed ImagesPotential savings of 15 KB (~80 ms)
The image compression check just looks at photo images and makes sure the quality isn't set too high. Images can usually be compressed pretty substantially without any noticeable reduction in visual quality. Source: Lighthouse - Learn more

Uses Progressive JPEGsScore: 0 %
A progressive JPEG is image created using the JPEG suite of compression algorithms that will 'fade in' in successive waves of lines until the entire image has completely arrived. They show the entire image right away, looking slightly pixelated until the image data is fully loaded. Source: WebPagetest - Learn more

Eliminates render-blocking JavaScript and CSS in above-the-fold content
This rule triggers when detecting that your HTML references a blocking external resource / file in the above-the-fold portion of your page. Source: PageSpeed Insights - Learn more about JS - Learn more about CSS
Your page has 14 blocking CSS resources. This causes a delay in rendering your page.

Improves server response time1
This rule triggers when detecting that your server response time is above 200 ms. Server response time measures how long it takes to load the necessary HTML to begin rendering the page from your server, subtracting out the network latency between Google and your server. Source: PageSpeed Insights - Learn more
Avoids landing page redirects1
Redirects trigger an additional HTTP request-response cycle and delay page rendering. In the best case, each redirect will add a single round trip (HTTP request-response), and in the worst it may result in multiple additional roundtrips to perform the DNS lookup, TCP handshake, and TLS negotiation in addition to the additional HTTP request-response cycle. As a result, you should minimize use of redirects to improve site performance. Source: PageSpeed Insights - Learn more
