Do you use anything like iStat Menus? It's a fantastic little toolbar application that can show you when things are spinning out of control, like you forgot you had a VM running, heavy disk I/O, or memory pressure.

Terminal is pretty low-key, but sometimes sub-processes of Terminal get lumped into the Terminal.app memory footprint in some visualizations. That means running a Docker VM can make it seem like Terminal is a huge hog.

The biggest pain is scroll-back buffers, but that's only a factor if you have them set to unlimited and are doing something like tail -f on a very busy log file.
