are you talking about Raytracing or OpenGL?

If you are talking about Raytracing, it is normal that rendering will 
take long... it is a feature for realistic screenshots, not for normal 
inspection, or at least that is what I would have expected...
i.e. if you do realistic rendering in Blender you have to wait quite 
long time to get the result to obtain a real 'realistic' view...

I compared Mario OpenGL viewer (with cache) and the recent 6558 revision 
of 3d-viewer and I get almost 1/10 rendering time in favor of Mario 
version... (these results on a mobile win8-64b with a modest graphic card)
