This is not to say that Next.js slacks – it's fast, just that Gatsby seems to eke out more speed more often than not, as per the data.

Site Speed Comparison

Talking about site speed comparison, the speed of a website can depend on many variables, including the server's response time, the time it takes to download and parse files (images, CSS, JavaScript), the speed of the user's internet connection, and even the device they're using.

As per real-world data available, Gatsby websites load faster resulting in higher Lighthouse scores compared to Next.js websites. It's not an enormous margin, but it's a metric you can't ignore if top-tier site performance is a primary requirement for your project.

Common Features Impacting Performance

Several features common to both Next.js and Gatsby impact their overall performance. Delivering optimized content, serverless features, hot reloading of content and code, modern development practices like the use of Sass and modern JavaScript syntax, and security features like XSS protection and access control all contribute to the resulting performance of websites built with these frameworks.

Both Next.js and Gatsby follow best practices and modern trends in web development, such as accessible markup, componentization, and one-way data binding, which can impact a website's performance positively.

Odd as it may seem, choosing one over the other can often lead to trade-offs in performance, depending on your project’s individual needs. Just know that you’re getting a lot of performance optimization upfront, regardless of which framework you settle on.
