Reminder that not only are Electron apps slow, but they also rely on proprietary software (portions of the chromium codebase). Atom, VSCodium, Riot "Desktop", are all guilty of this. All of them ping home to Google because of this.
Also related: There is nothing cross platform or native about releasing your web app in a little Google Chrome window. Frankly, that's just a deceptive claim. If it can be locally run in a browser, release it that way so the user can use their own browser.
