Defense.Gov is a popular website in the Science/Technology category. According to the latest CWVIQ speed report, Defense.Gov took 0.04 seconds to load the page. Anything over 5 seconds means that the website is too slow to load.
A slow load time could be due to a lot of things – poor network connectivity at your end, an unreliable hosting server, or a poorly optimized webpage.
First off, let’s look at a breakup of the loading time.
|DNS Lookup Time
(Time taken to lookup the IP address of the server)
(Time taken to establish a connection between your server and the server where Defense.Gov is hosted)
(Time taken to verify server credentials by comparing public key with its digital signature)
(Time it takes for the website’s server to process your request)
(Time it takes for the requested data to be transmitted to your server)
A high value for DNS lookup or TCP connection could be because of local settings, or internet connection.While a high server processing time or content transfer time could indicate issues with the website or its server.
We also studied the Defense.Gov Lighthouse report to look at the site’s performance. Here is what we found.
|Speed Index – Time for the page content to be visibly populated
|Server response time
|First Meaningful Paint – Time for the viewable content to be rendered to the user
How To Make Defense.Gov faster
Here are the top 16 ways to make Defense.Gov faster.
1. Largest Contentful Paint – 2.39 seconds
Largest Contentful Paint marks the time at which the largest text or image is painted.
2. Time to Interactive – 2.31 seconds
Time to Interactive is the amount of time it takes for the page to become fully interactive.
3. Minimize main-thread work – 2.24 seconds
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
4. Properly size images – 1.88 seconds
Serve images that are appropriately-sized to save cellular data and improve load time.
5. Speed Index – 1.83 seconds
Speed Index shows how quickly the contents of a page are visibly populated.
6. First Meaningful Paint – 1.69 seconds
First Meaningful Paint measures when the primary content of a page is visible.
7. First Contentful Paint – 1.59 seconds
First Contentful Paint marks the time at which the first text or image is painted.
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
9. Eliminate render-blocking resources – 0.5 seconds
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
11. Reduce unused CSS – 0.24 seconds
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
12. Serve images in next-gen formats – 0.24 seconds
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
13. Max Potential First Input Delay – 0.18 seconds
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
15. Total Blocking Time – 0.07 seconds
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
16. Minify CSS – 0.04 seconds
Minifying CSS files can reduce network payload sizes.
In addition to these reasons, here are other ways to make Defense.Gov faster.
Cumulative Layout Shift – 0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Avoid enormous network payloads – Total size was 5,354 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Uses efficient cache policy on static assets – 3 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoid an excessive DOM size – 1,546 elements
A large DOM will increase memory usage, cause longer
