I think it's unlikely the performance issues are related to the underlying tech (that is, Electron), since it's basically a custom build of Chromium that omits the normal web browser controls. Performance-wise, if your app is suitable for running in a browser, it should be fine for bundling with Electron.

As noted in a sibling thread, other Electron apps such as Spotify and Slack do suffer from performance issues, and the general notion is that Electron apps are "slow by default" - that is, slow unless you take explicit effort to make them fast.

Since when are programming editors handling large files and IDE-like features "suitable for running in a browser"?

I know there have been several (browser based programming editors) over the years, but all have been equally crappy and slow on medium to large files, and not that better at normal workflows either.
