Performance History

Knowing how your site performs over time is a valuable tool for monitoring and maintaining an effective website. See how key metrics perform over time and enable/disable specific metrics to focus on the areas of highest value. Go even further by comparing specific points in time to see the changes that occurred between them.

 

In the performance history view, you can choose any point in time to see your site’s or page’s performance stats at that time in detail.

 

Browser Waterfall

Review a detailed breakdown of the page loading process in the browser waterfall diagram:

 

In the browser waterfall view, you can take a closer look at all the elements that need to be loaded in order to show your page.

 

Using this view gives you a breakdown of the page loading sequence, accompanied by screenshots of what the browser is showing at each point. This enables you to drill into the loading sequence at any point in the page load lifecycle. Clicking on any part of the report shows an expanded view with the detail of the assets loaded and whether a script - video, font, or even third-party integration - is blocking execution, potentially causing rendering delays.

 

Cumulative Layout Shift

The visualization of the Cumulative Layout Shift (CLS) metric can also be invaluable for troubleshooting your loading process. It allows you to see exactly when and where unexpected layout shifts occur during the page's lifespan. These shifts can be disruptive to the user experience, leading to accidental clicks, difficulty in reading content, or general frustration. By identifying and addressing these issues, you can significantly enhance the usability and accessibility of their site. Moreover, since Google includes CLS in its Core Web Vitals affecting SEO rankings, optimizing this aspect directly contributes to higher visibility in search engine results.

 

In Niteco Performance Insight, users can hover over a screenshot of the page in the loading process and see the difference to the previous frame, making layout shifts stand out.

• Eliminating render-blocking resources - refactor your code to remove render blocking.
• Using next-gen image formats and reducing image sizes - reduce the amount of data to be transferred.

These myriads of data and prompts at your fingertips enable your development team to take a deep dive into performance over time. This is an essential tool for diagnosing issues and optimizing performance.
