I recently added some Maya 2009 scene files to our benchmarking database.

I'm hoping to get more Maya users to participate in the project. As it is, I don't have many benchmarks for Maya. For those unfamiliar with the project, we're trying to build a massive benchmarks database open to all 3d apps and render plugins. If you have some spare time, please head over and submit your render time
