Mount /tmp as ramdisk
To increase performance on your linux box and decrease IO waits for applications that use /tmp, you can mount it as a ramdisk. The process is simple, just keep in mind that it gets cleared any time a system is rebooted.
Open fstab using whatever editor you prefer:
sudo vim /etc/fstab
Add the following line at the bottom:
none /tmp tmpfs defaults 0 0
Save and exit.
If you have /tmp already mouted as a separate partition, comment it out in the fstab.
Reboot your system.
You can also optionally specify the size of the partition (the amount of RAM to use). This is not necessary and probably best to let your system manage the memory.
none /tmp tmpfs defaults,size=512m 0 0

tmpfs is not ramdisk. I was looking for the info, but this is misleading to readers. If I find it I will return to comment more constructive.
