Bug Description
Binary package hint: blender
Rendering on 64-bit ubuntu is much faster than on 32-bit xp (up to 40%). However, raytracing in ubuntu is really slow, so slow it can be considered as a bug, because windows can render at multiple speed compared to ubuntu when that option is enabled.
Testing:
- Render a scene without ray tracing and compare the rendering times with xp and ubuntu and notice how much faster the latter is.
- Re-render but now ray tracing enabled. Make sure that most large objects on your scene are reflective and transparent.
Both operating systems are now rendering slower than without ray tracing but ubuntu almost stucks.

Is this a graphic driver issue?
This sounds like using optimized drivers (e.g. the non-free nvidia-glx(-new) drivers for Nvidia) could make a difference?
