When you work with a lot of object, the computer will certainly be heavier "reading" these objects, due to the large number of Segment owned by each object. How can I make these objects have a number of segment slightly but the shape still looks smooth and not rigid / damaged?
Here's a guide:
Step 1
Make 2 pieces Teapot with the same magnitude and the number of each of its Segments are 12. Enable Perspective Viewport and press the F4 key to display the mode edged dikeyboard Faces.
Figure 01.
Step 2
Teapot you select on the left and give the Optimize Modifier from the Modify tab. You will see the Teapot object will find a reduction in the amount of its Vertex-Vertex and Segment visible change its shape by not affecting the Teapot shape as originally
Figure 02.
Step 3
Note Optimize Status Last section, you will see the number of its Vertex and Face before and after the Optimize Modifier.
Figure 03.
Step 4
Do Render. Teapot you still find the same object, but with a little amount of Vertex.

Rendering results
