Dear George,
I think it will depends on the amount of memory that each your session will
need.
Case each session use a big amount of memory, may be your some of your
sessions will get error. I also think that you will not save time if you
start several dataset at same time, because windows is windows. By other
side, I think that on linux you can get better results.

Good luck.
