The max and fbx files contain 3 tables of different diameters: 100, 120, 135 cm, height 75 cm.

In a MAX format file:
Polys: 1,648
Verts: 1,654

OpenSubdiv modifier (2 iterations) is open for rendering.

In an FBX file:
Polys: 26,368
Verts: 26,374

OpenSubdiv modifier (2 iterations) is open.
To make the scene lighter, reduce the number of iterations from 2 to 0, and increase the render iterations from 0 to 2. In this case, the number of polygons and vertices will be reduced to the values specified for the max file.
