Adding CPU cores to guest decreases performance

Description

I'm running Linux Mint 13 (maya) lts x64 linux Kernel 3.2.0-35 generic on a dual processor 4 core machine Xeon 5340 , w/16 gb memory. Vbox version is 4.2.6 r82870

The guest I'm having issues with in MS Windows Server R2 x64. When I configure the machine for 1 or 2 cores it functions normally, but I find as I add additional processor cores each addition reduces guest responce. to the point of taking hours to do a simple task.

Is there any way to fix this problem.
