Mounting /tmp on ram disk



I am trying to squeeze better performance using the /tmp directory.

The first option : "ln -s /home/tmp /tmp" so it will be in the same file
system as
the home directories and so all the operations that create a temporal file
the then
move it will really move inodes and not copy the file.

The second option (as seen on SunOS) - mount the /tmp on a virtual files
system
resident in the swap. It actually a ram disk that can extend to the swap
partition
when needed.

Do you know which one is best ?
How can I (simply) do the second option in RedHat 7.1. Should I patch the
kernel ?

Tnx,
