Lots of RAM (at least 8 GB): put /tmp on tmpfs
9. Does your system have lots of RAM memory? If it has at least 8 GB, then you can probably speed up your system a bit by placing /tmp on a tmpfs partition. Which means, translated into ordinary language: you bring about that temporary files will not be placed on the hard disk anymore, but on a virtual RAM disk instead.This is how you do it:
a. Launch a terminal window.
(You can launch a terminal window like this: *Click*)
Copy/paste this blue line into the terminal (it's one line!):
sudo cp -v /usr/share/systemd/tmp.mount /etc/systemd/system/
Press Enter. Type your password when prompted; your password will remain entirely invisible, not even dots will show when you type it, this is normal.
b. Then copy/paste this command into the terminal:
sudo systemctl enable tmp.mount
Press Enter.
c. Reboot your computer.
d. After the reboot: check whether it works, with this terminal command:
systemctl status tmp.mount
By default, a tmpfs partition has its maximum size set to half your total RAM. The actual memory consumption depends on how much you fill it up, as a tmpfs partition doesn't consume any memory until it is actually needed.
Note: do not apply this on systems with less RAM than 8 GB! Because then this tweak might not make them faster, but (much) slower.
How to undo tmpfs
9.1. Do you wish to undo tmpfs? Then copy/paste this line into the terminal:sudo rm -v /etc/systemd/system/tmp.mount
Press Enter. Type your password when prompted; your password will remain entirely invisible, not even dots will show when you type it, this is normal.
Afterwards, reboot your computer.
