I would be interested in seeing vim, nvim, and emacs performance using a slew of plugins to get to the point where their functionality is close to the features that sublime/atom/vscode have out of the box.
Emacs has many of those out of the box, you just need to tweak/enable them. The worst thing about Emacs is it's default settings, because the whole point of it's existence is customization to very niche and personal needs.
Same. I'm not really sure what it is, but the moment you add a few plugins to vim, you definitely notice a slowdown. I'm sure it's the abomination that vimL is.
I do use plug, actually. It was more a complain to the fact that the editor does feel a bit sluggish sometimes if you have a few plugins on. I think vimL is a pretty darn slow language (not to say that it's probably one of the worst languages I've ever touched).
I wouldn't, because none of that functionality is/should be involved in the simple tasks that were benchmarked in the article. If it still slows down these things by orders of magnitude, it has to be implemented sloppily, don't you think?
