Scanning in NIS 2011

I scanned my whole PC at one time and 1.836.747 takes 34:39 minutes. I wanted to see if NIS uses my multi processor effective. I'm disappointed. I also scanned the PC (is the same) by station. 

C = 483.348 files  17:17

D = 305.309 files  13:51

E = 1.034.380 files 23:33

So after 23:33 minutes the job is done. This is 11:06 minutes faster! Why can't NIS 2011 figure that out if you use multi processor. See signature for system.
