370 not 270. In the other test it loses, so it's not really conclusive.
It's true you have to load up more code for electron, but not everything in the chrome package is code and lots of it gets mmapped anyway. A large part of the memory usage for the electron/Tauri apps is the chrome heap and loaded app resources - that doesn't get deduplicated. An empty chrome (just started with no tabs or extensions) uses 350MB of RSS memory for me. That's going to be slightly lower for electron, but that value will be the lower bound for every single electron process started.
