This sentiment, that Atom is not performant because it's built on web technologies, gets repeated a lot, but it's provably false. Light Table and VS Code both use the exact same HTML/CSS/JS stack on top of Electron. Both are much more performant than Atom. Whatever performance issues plaguing Atom are more likely caused by flawed architecture and/or lack of optimization. The underlying web technologies it's built on have been demonstrated to be capable of delivering highly performant text editors.
