I don`t know if tmpfs is related to RAM but my ram was constantly on about 30% it never reached 100%

@dr460nf1r3

It is, it basically stores the files an RAM.

OP provided the details

@unxtres

I have changed size of tmpfs, by default it is 10% from total RAM installed:
sudo nano /etc/systemd/logind.conf
uncommented and changed entry:
RuntimeDirectorySize=10%
to
RuntimeDirectorySize=8G
then
sudo systemctl restart systemd-logind

It can be adjusted by SysAdmin to usage priorities and hardware capabilities.

@dr460nf1r3

you can disable psd entirely

or configure a percentage of RAM, as suggested.
