Reduce initial server response time is one of Lighthouse's performance audits. It evaluates the time it takes for the browser to receive the first byte of the root document (usually the main HTML file) from the server, excluding the connection setup time.

To pass the Reduce initial server response time audit, you'll mainly need to focus on your hosting environment, caching strategy, and backend performance optimization.

In this article, we'll look into what initial server response time is exactly, how it hurts web performance if it becomes too long, and how you can pass this Lighthouse audit.

Lighthouse (LH) is a free, open-source website analysis tool from Google that allows you to generate a report, which includes a list of audits that evaluate how well a web page scores on various signals.

When developing a website optimizing web accessibility ensures that you don't limit the number of people who can use your site. An accessible website not only helps users with a visual or hearing impairment but also means your website can be used with the keyboard and on a wide range of devices.

Lighthouse tests usually perform a non-interactive cold load. However, real users interact with the page, and load pages again with some resources already cached. User flow support in Lighthouse lets you test sites beyond the initial page load.

Lab-based performance tests often give different results from data that's collected from real users. This article explains the differences between these two ways to measure site speed and how they lead to different test results.

We'll focus on Lighthouse and the Chrome User Experience report, but note that there are many other ways to collect lab or field data.

Google released Lighthouse version 8 this week. This article looks at how the Performance score and Lighthouse report have changed compared to version 7.
