Much has been written about how Electron apps take a lot of memory; after all, each one is running its own instance of a web browser, and pulling in all of the overwhelming amounts of support code that implies.

Well, I’ve figured out a way of getting these chat apps to take half as much of my total RAM overall, but first, let’s talk about my personal history of memory usage.
