This one may be a good application for the Path Tracer (Lighting->Advanced). It will start out very noisy but may converge quicker.

You can try turning off Monte Carlo to see how the default engine deals with the glossy reflections -- OR-- you can also try some of the other Reflection Shaders in the Material Editor (turn off Monte Carlo if you do this.) If you opt for the Path Tracer none of these settings will matter.

thank you! I try the path tracer, the white noise is cancel, and I try the light trough, I am very satisfied, but the renderng time too slowly. Can I to do anything to modify my system.

I am using intel 6 cores, windows 7 32bit, I will upgrade it to windows 7 64 bit., and acad2011

thank you very much

The upgrades you mention are good ideas, but probably will not help performance in this case. More (and faster) cores will help.
