Why does Bitwarden self-hosted use so much RAM? And is it possible to tweak settings to make things better? (Proxmox VM)

Although the minimum recommended RAM is 2GB, my self-hosted installation is constantly using 2.8 to 3GB. It seems strange to me that software of this nature is always using that much memory, and I’m wondering if there’s any way to tweak things to make it run better?

I have Bitwarden running in a VM on a Proxmox server, and it uses more RAM than almost all of my other VMs and containers, which really doesn’t seem right to me.
