No. Rendering happens in the 3D hardware of your PC and requires a certain time for processing the mesh. This time depends on the mesh size, the speed of your hardware, and the rendering method, f.i. a shader. When you render it twice, as in 2 views, naturally you'll need twice the render time.
Other time factors such as ABT clipping and lighting do not necessarily double with two views - there are view flags to let the view know that the ABT was already processed. The PSSM shader takes advantage of this, so its multiple views render much faster than they would if they were single views.
