ramdisk

i've made a ramdisk this way:

mkdir -p /media/ramdisk
mount -t tmpfs -o size=512M tmpfs /media/ramdisk/

The reason for this is because i run a lot of node.js scripts and their execution time is very small, but i suspect that the time overhead is because it reloads the node.js executable from disk and destroys it on each subsecuent run. So i think this might be the solution to gain a bit, if not much, performance. How can i move a program like node to the ramdisk and run it from there? The idea is to have a startup script that creates the ramdisk and puts the node files inside of it. Note that i'm currently using fedora 16 for what's it's worth. Thanks in advance.
