 ====== BASH - Directories - Place /tmp on a tmpfs partition ======
+<WRAP important>
+**WARNING:**  Only follow these instructions if your system had at least 4GB memory!
+Because then this tweak won't make them faster, but (much) slower.
+</WRAP>
+Speed up your system a bit by placing **/tmp** on a tmpfs partition.
+Any temporary files will not be placed on the hard disk anymore, but on a virtual RAM disk instead.
+----
+<code bash>
+sudo cp -v /usr/share/systemd/tmp.mount /etc/systemd/system/
+sudo systemctl enable tmp.mount
+</code>
+Reboot your computer.
+After the reboot, check whether it works:
+<code bash>
+systemctl status tmp.mount
+</code>
+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.
+----
+===== To undo tmpfs =====
+<code bash>
+sudo rm -v /etc/systemd/system/tmp.mount
+</code>
+Reboot.
