On a Unix/Linux/BSD device /tmp tends to see heavy usage. I’ve moved mine into RAM to ever-so-slightly improve performance and more significantly reduce SSD I/O.

To do this I edited

/etc/fstab

as root with my favourite editor. I added the following line at the end:

tmpfs           /tmp            tmpfs   defaults,noatime  0       0
tmpfs           /var/tmp        tmpfs   defaults,noatime  0       0

You can reboot at this point and you’re all set. You could manually mount this but it could cause problems with your system.

UPDATE: Ubuntu and Lotus Notes for Linux don’t like mounting /tmp as nosuid and noexec.

Let me know if you do this and how it works for you.
