Write better code

Try to reduce your bundle sizes

The first thing you can try is using dynamic imports (see the nextjs docs)

In other words you only load the essential components for your site on first render, and the rest are loaded after the response is sent

Your total response time won’t decrease overall, but your performance score should since a user will see content sooner

Also you can to analyze your bundles using webpack bundle analyszer (there’s a plugin for next) to see a visual representation of what you’re bundling and try to eliminate unnecessary stuff
