Performance improvments for OS X

Before LR 1.2 i was using Bridge to manage my images. Now with CS3 and LR, I've been comparing the two. One big thing that strikes me is the way LR causes my G5 (2.5 GHz, 6g ram, OSX 1'.4.1') to kick in to "heavy overdrive" whenever I interact with a group of images.

Apparently LR is doing some HEAVY lifting as the fans on the G5 kick into "jet engine" mode and scream away furiously for maybe 2 or 3 minutes. Especially during imports. And the fans noisily kick in from time to time when just browsing and reviewing images.

Bridge CS3 (gross folder icons aside) pops the thumbnails into view with only the bares twitch of the fans.

I think the Lua language LR was written in may be somewhat responsible for these performance shortcomings.

What are your Bridge thumbnail prefs set to? If it's Quick Thumbnail or Convert to High Quality When Previewed it won't take as much juice to run it. Previewing a lot of files at high quality in Bridge can get my MBP running pretty well. I've found LR to be much faster to import and display pictures. I've tried using Bridge on a photo shoot, and it was painfully slow when dealing with large numbers of images.
