I'm using HUB 2.3.1. Why there are multiple "Unity Hub" background processes? The number of Unity Hub background processes varies. Sometimes it's 2, 3 or 4 sometimes even 5. My PC doesn't have a lot of memory, so those wasted megabytes count for me. Why does a program have to use almost 300 mb for just sitting in the background idling? Would be nice if you can tame this memory hungry beast.
