Thanks, I'll look up on this. Have a few machines that would most probably benefit from this.
Amazing, this temp-cache-in-RAM is a déjà vu from my OS/2-days some ten-ish years back... Never thought I'd use the same techniques now as then. 8-)

One thing that's not clear in the two links that have been posted about doing this is, do you add the line or replace the the line already present in /etc/fstab?
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 <---------- none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0
Thanks

Here is what I put in my fstab:
tmpfs /tmp tmpfs defaults 0 0
And your done. By default it will use 1/2 of your memory and under pressure it's first to swap and even if you run off swap it gives comparable performance to the way it is now.

Do I leave this line in tact or remove/replace it:
none /dev/shm tmpfs

No, leave the existing /dev/shm, some apps depend on it.
You can use the 'none' keyword too for /tmp as in:
none /tmp tmpfs defaults 0 0
Either 'tmpfs' or 'none' should work.
