Anyone test DxO Optics Pro on MacBook Pro w/i7 CPU?

As the subject line suggests, I'm interested in knowing if anyone has tested the processing time of DxO Optics Pro (v5 or v6) on a MacBook Pro with an i7 CPU. My experience has been that each of my Nikon D90 raw photos takes around a minute and a half to process on my Dell 6400 laptop running a 1.73 GHz Centrino Duo with 2 GB of RAM (processing two photos at a time, one on each core). I'd really like to know what kind of speedup I might see on a MacBook Pro with an i7 CPU, with 4GB or 8GB of RAM, processing 4 or 8 photos at a time.

If you decide to reply, I'd like to know the CPU type and speed, RAM size, hard drive speed (5400 or 7200 RPM), DxO Optics Pro version, and image type and size so I can make sure I'm comparing apples and some other known kind of fruit. I'd also like to know how many images at a time your DxO Optics Pro is set up to process.

Thanks!
