Fair enough, you mentioned the speed of adding a package and I assume it was the build time after the download (which is mostly git). I have to confess that I don't consider the speed of the initial build essential since it's a one time thing (correctly and efficiently building and handling dependencies is, which it does very well in my opinion). Also, I think they are testing now a way to deliver binary libraries within the deps which can improve the situation with the external dependencies. Visual Studio Code is definitely fast enough in my machine (especially with a Revise.jl workflow), which is why I also assumed it was stuff like running part of the code or using the Language Server Protocol, which will hit the same compilation lag. I agree that Atom is slow, and it's one of the reason I don't use it. Though I'm clearly biased since my experience is entirely in Linux, it's possible that the Windows experience is just worse.
