> try to run more than two Electron apps at a time and tell me if you don't feel the slugginess

I run more than two Electron apps at a time and everything is fine.

Unless you’re running ancient hardware with 4GB of RAM and trying to load up many intensive applications (Electron or otherwise) it’s not a problem. If anything gets “sluggish” then you’re probably swapping, but it’s difficult to actually reach that point with just two Electron apps.
