It’s a slight exaggeration, I also have an editor open and some dev process (test runner usually). It’s not just caching, I routinely hit >30 GB swap with fans revved to the max and fairly often this becomes unstable enough to require a reboot even after manually closing as much as I can.

I mean, some of this comes down to poor executive function on my part, failing to manage resources I’m no longer using. But that’s also a valid use case for me and I’m much more effective at whatever I’m doing if I can defer it with a larger memory capacity.
