I think OP is both right, and there was people still complaining about it. Atom was seriously slow. Everyone said you couldn’t build a fast text editor that could compare to native ones. VS Code came and it was significantly faster Atom was slow to the point of not being usable to some, while VS Code was perfectly usable. The people wanting vim or Sublime performance were still upset and wrote about it, but vscode was perfectly usable and fast enough for the majority of people. It was indeed held as an example of how to make a performant electron app. Still an electron app, but not absolute slog. Tbh, if you disable all extensions in vscode, it’s still fairly fast, and doesn’t even take that much memory. It’s not as usable without extensions though.
