Can I place my application code on partition in my RAM?

Question

I want use RAM instead of SSD. I'm looking for experienced people to give me some advice about this. I want to mount a partition and put into it my Rails app.

Any ideas?

UPD: I tested the SSD and RAM. I have a OSX with 4x4Gb Kingston @ 1333 RAM, Intel Core i3 @ 2,8 Ghz, OCZ Vertex3 @ 120Gb, HDD Seagate ST3000DM001 @ 3Tb. My OS installed on SSD and ruby with gems placed in home folder on SSD. I create new Rails app with 10.000 product items in sqlite and create controller with code:

@products = Product.all
Rails.cache.clear

Tested it with AB.

So, I think that thing in ruby with gems placed on SSD and get this scripts slowly, I will test on a real server and puts all ruby scripts into RAM with more complicated code or real application.

ps: sorry for my english :)

You are looking for a ramdisk.
