Not in my experience.

If you set up volumes for node_modules or any folders where where dependencies are stored you get the same performance on Mac as anywhere else.

For rust, which I use, I'm able to get better performance on Mac under docker than using rust tools natively. See https://purton.tech/blog/faster-rust-incremental-builds/
