Yeah, if you got the ram this should be pretty good.

I'm wondering about the size of the partition though.
I've heard that tmpfs is dynamically resized. With this kind of approach, 
wouldn't it be a good idea if it was possible to set the partition to a 
specific size? This to avoid putting to much in the partition and causing the 
machine to start swapping.
Or is it already possible to specify a size for tmpfs partitions?
