I noticed this line was missing from fstab so I added it:
tmpfs /tmp tmpfs nodev,nosuid 0 0
Is it a good idea. I want my apps to start faster but they somehow seem to start slower...I'm using Plasma btw.
Thank you.
This uses your RAM as /tmp and it's way faster than using a HDD or even a SSD. If you don't use /tmp for user stuff (i.e. temporary downloads and such), the RAM usage is negligible and not causing adverse effects even in low-RAM systems.
