maya 2010 laggy when performing certain operations.

Just wondering if anyone has noticed maya 2010 being laggy. For example when I duplicate a cube it has to think about it for 1 second. Easy way to test this, duplicate as many cubes as you can ctrl d and try to move it immediately. It seems to access the hard drive each time I duplicate as well? Went back to maya 2009 and the problem does not exist. Other shit is laggy too, selecting edge loops and other common shit. Anyone else notices this lameness?
