If you watch a lot of youtube video's or run a lot of programs that cache to /tmp you will notice that it can be incredibly slow while multi-tasking because the other programs are using the disk too. As long as you have enough ram you can mount /tmp as to your ram. However, use at your own risk - programs that cache backup data to /tmp (Like firefox [although open office does not]) will not be able to restore your previous session after rebooting. If that is no problem then continue on reading.
Open your /etc/fstab as root in your favourite text editor (I will be using gedit because it is by far the most simple) by launching it from the terminal.
Code:
sudo gedit /etc/fstab
Add this line to the end.
Code:
##RAMDISK##
none /tmp tmpfs defaults,size=424m 0 0
You can change the size to whatever amount you want in megabytes but do not go over half of your ram. <Ctrl>+<s> and <Ctrl>+<q>
Reboot, yes this is needed, you can mount -a but its pointless because then your xserver will crash because the display property will become unset.
Enjoy much faster website loads!
Also a tip for youtube users, the video is stores in /tmp so you dont need to use a flash down-loader to save a youtube video - just copy the file to your folder of choice after watching it.
EDIT*
The size parameter is optional as I have found out from experience so you might want to use this instead to save RAM!
Code:
##RAMDISK##
none /tmp tmpfs defaults 0 0
EDIT**
Okay I just found out how to do this without rebooting but its not quite as simple. Continue from the last step before rebooting, exit everything, and <ctrl>+<F1>. Enter your username and password. Run these commands.
Code:
sudo -i
gdm stop
rm -fR /tmp/*
mount /tmp ##or mount -a
gdm restart
EDIT***
Do not use this trick if you use proprietary types of enterprise software, because they store files in /tmp for security reasons.
