Since the upgrade, I've noticed macOS doesn't like to give up memory as easily. I currently have 32 GB of RAM installed, only have Safari (one tab), Activity Monitor, and 2 very lightweight non-leaky menu bar apps open, aside from system daemons and such but it shows that I'm using 14 GB of 32 GB of RAM. None of which is purgeable through the terminal. macOS has never been this liberal with the amount of RAM it gives to apps and I'm curious as to if anyone else has noticed this since upgrading. If not it may just be grounds for a re-install but I'd like to see what the community has to say before I do that as I have almost 1.5 TB that I'd have to restore.
