Thanks @vanvugt, this was helpful. I'm running ubuntu 23.10. It's been about a week since I rebooted and I noticed swap usage was quite high. I've got 32GB of RAM and am a developer with a bunch of stuff open at once. Decided to investigate. Closed everything, but left just gnome running and a terminal. Did a swapoff -a to clear swap and dropped caches to get it as close to just what was allocated as possible. It still showed 14GB of memory used with 5GB in cache. That seems high.
So, ran this to take a look at VmData for gnome-shell: cat /proc/$(pgrep -f /usr/bin/gnome-shell)/status | grep VmData That reveals: VmData: 1231000 kB That seems a bit excessive. Full disclosure. I do use extensions. It's too bare-bones without them. I miss being able to Alt-F2 -> R and reboot gnome, but it appears to not be possible now with Wayland. > It's important to remember that RSS increases is no indication of a leak - it > will rise and fall according to how busy the machine is and not how much new > memory the process has allocated.
