Zanthor thanks for the info.

I think I figured out hotstrings. There are some keys on my Priest account I did not want passed to my mage account but I wanted passed from mage to priest. I did some keymapping and associated it with his command file and he no longer passes those key strokes over. I am still unclear about the core thing. I have the new I7 and it has 8 cores. Back in the day playing games like the Realm and setting core affinity helped with memory leaks and such. Does setting the core improve performance or stop the wow memory leak? As it stands with the core I7 and two instances I am only using 17% of my CPU.
