Performance

Performance introduction¶

The Acquia Optimize Performance add-on helps users improve website load speed and performance. You can youw statistics on how your website performs for visitors in different locations, on different devices, and how they connect with different network speeds. Acquia Optimize automatically identifies and provides feedback about elements that slow down the website.

Page scans are based on selections made by the user. Make adjustments based on a large number of settings that determine how the scan is performed, such as location, speed, and device type. When a scan is finished, the results are integrated and can be viewed and analyzed in the Page Details view.

Google Lighthouse¶

The Acquia Optimize Performance add-on is based on Google's Lighthouse API v10. Google Lighthouse is an open-source API and a powerful tool to help users improve the quality, performance, and correctness of web pages. Users can input a URL and receive a score along with suggestions for how to make website performance improvements.

Google’s online service software assesses Performance, PWA (Progressive Web Apps), Best Practices, Accessibility, and SEO. In our first version, Acquia Optimize has only integrated the Performance part of Lighthouse.

With the Google service, users need to enter each URL every time they want to see a score. The Acquia Optimize Performance module improves upon this with the possibility to set up score result sequences, for example, Acquia Optimize can automatically scan the selected page up to 4 times per day.

How Acquia Optimize can help¶

Google’s current Core Web Vitals include Largest Contentful Paint (LCP) which is similar to FMP, First Input Delay (FID) which is often, but not always, correlated with TTI, and Cumulative Layout Shift (CLS) which looks at how many times the layout shifts during the entire lifecycle of a page.

While there are some additional factors to consider with the upcoming Core Web Vitals algorithm, if you tackle the issues highlighted by the Acquia Optimize Performance module, you will still make improvements to the page that will improve the user experience and likely improve upon these core web vitals.

Google has made visibility into their evolving Web Vitals available through as many relevant tools as possible including their Chrome User Experience Report, PageSpeed Insights, and Search Console. These are all free tools. For more information on ways to make improvements, they also offer a number of guides for optimizing the following:

• LCP
• FID
• CLS.
