Hi there, I have both systems on a DELL 64bit machine. I compiled R 2.9.0 on both systems, to get 64bits capability. Surpriselly, on Linux (Ubuntu with I installed 3 month ago) I spent 41s to run the same test you did, and less time (35s) under Vista. In fact I had noticed that I not have gained time when running under linux (I had done jobs that run for several days). But somethings I gain with memory managment, because for some programs or steps, windows say that memory is full, while Linux run up to the end of the job.
