LR Performance Suggestion - Develop Module

I've been a Lightroom customer since V3 was released, and currently use LR4.1. The Develop module has always been a bit slow to load images, and has gotten far worse with large (45MB) RAW files from the most recent Nikon DSLR. On a Win/7 64-bit PC with 8gb memory and a Core i7-920, I'm seeing 8-10 seconds before "Loading" disappears. This is a significant performance issue.

The loading process in the Develop module puts a fair bit of strain on a CPU and disk drives, but once "Loading" is complete, the system essentially sits idle while the user reviews and edits the image. Rather than wasting this idle time, it should be used to improve the perceived performance. One way would be to run a background task that pre-loads and/or buffers adjacent images along the filmstrip. For instance, if image # 10 is being edited, it would be reasonable to pre-load and/or buffer images 7-13 so that they would be ready to go when the user moves to an adjacent (previous or next) image along the filmstrip.
