It doesn't matter which framework really, any improvement is much better then what we currently have. WhatsApp on Mac currently uses 1GB Memory sitting there doing nothing. Not too bad for an Electron App I guess since Telegram uses 650MB after being opened for 48 hours, but it does sit at 150MB once it is closed and reopened.
And before anyone else say Memory were suppose to be filled, consider that paging actually lower the lifespan of a SSD, I have currently done 2TB of writing over the past few days.
