I am not sure...
  But my employer would like to get me a new machine and considering that R is the program I use most often, he was wondering what type of machine would be the  best to get form me.

  If you job is CPU intensive (it should be unless it is reading in data all the time, or does not have enough memory so it is paging).  Look at the amount of time you are paging.  Otherwise, it is probably using only 1/4 of the available processors if you system has 4 CPUs.  Do you know how many it has?

Soemtimes just creating the predicted vaules from the Bayesian analysis takes over a day to run! 
  I am just wondering if R runs faster on any particular systems or if it is about the same regardless.

  Need to know what you are trying to do with the data.  Depending on what you want to do and how you do it will determine the speed.  I can take a dataframe with 1,000,000 rows of transaction data and compute the average and plot a histogram of the response time in less that a couple of seconds.  Is that fast enough?

Can anyone answer this question.  I am working with really large datasets and most of the programs I have been running take quite some time. 

I heard that R may be faster in Unix.  I sthis true and if so can anyone reccomend which system and requirements may allow things to go faster for?

Thanks!!
