Idk, I'm having a good experience with Biome 2 in a large codebase. 4s to do a full-check including floating promises, undeclared and cyclic dependencies, and sorting imports. Our ESLint setup used to take almost a minute. The Biome team has been fixing bugs on a daily basis. Version 2.2.0 (released 3 days) ago addressed a common high-CPU-usage bug, try it out.

Edit: it's not 4s anymore, I just measured with the latest version and it takes ~900ms. Insane.

Are simply running eslint from the root of the project? And is this a monorepo?

I have used eslint in very large projects (far more than 3000 files) and running multiple instances via a task runner makes it a breeze to keep it under 30s or less, especially if you use the cache

I did try and it just stalls, taking down my CPU with it. I had moved onto other tasks and found it later still killing a few cores. It's in a monorepo with maybe 3000 files. I have no trust in the project.

Yeah I understand the frustration, I had issues setting up ESLint/Prettier years ago and spent a few hours getting the Biome configuration right. Also a monorepo with ~4000 TS/TSX files. If you ever feel like trying it again, make sure that you have "files.maxSize" and "files.ignoreUnknown" set. And be very careful with the "files.includes" list.

It sure would have been nice if biome used a better include syntax. I dislike the new way of doing it in biome 2, because it creates ambiguity and works differently than damn nearly every other tool I use
