[R] 32 vs 64 bit

I ran R on an AMD Athlon 64 with a 32 bit Linux (by accident, I moved the hard disk from another machine). Now, after install 64 bit Linux and 64 bit R, I am finding some of my R tests are quite a bit slower, I think because memory demands cause a lot of swap. Does anyone know if extra memory usage would be mainly because of R itself, or is there a lot of extra memory demand because of the OS, windowing system, and other apps?
