🚀 Feature Proposal

Hi, my project has a lot of routes ~100 routes and ~150 dependencies. And everything is slowing down. I used all tools nodemon , ts-node, ts-node-dev, backpack and fastify-cli (v4) I even purchase a new good CPU with a benchmark score is 24000 But my project still takes 4-5s to restart when a file is changed.

I am using Next.js too. And I am curious why Next.js never needs to restart the server, but other node.js frameworks can’t do that 🤔

Motivation

Everyone is happy.

I think it can do it because of money. Vercel pays devs to work on the Next.js framework full-time.

Vercel raises $150M Series D as it looks to build an end-to-end front-end development platform

@sidwebworks I just tested it, it is faster than ts-node but not faster than fastify-cli.
