when you say there is a 2 second lag time what exactly do you mean?

your in develop with the adjustment brush open, and when you highlight and go to another picture with the brush still open it takes 2 seconds to render the picture? is it a 1 to 1 preview?

does the 1 to 1 preview already exist?

if you just have a 1 to 1 preview open and no brush open does it open faster?

mine is near instant but I have a SSD drive & my pics on another stripe

Camera raw cache is 50gb of the raid0 disk.

I've even tried moving the catalog into a 10k rpm raptor drive. No cigar(actualy, this 1st gen raptor, hdtune saw the numbers being worst compared to a 7200rpm drive)

All imports are into a new catalog. Average size of each catalog (each import) is like 2.5k raw photos of 18mp each ~25mb file.

Video card is an ATI radeon w/ 1gb ram. ATI 4850 or something like that. Cant remember the numbers.

Actually, the lag is bearable, but if I can do something about it, I would. Actually, have regretted a little bit in getting the off-the-shelf acer m7710 PC. Now I cant even do any simple over clocking. A modest increase in CPU speeed should help plenty I presume. As I see the CPU spiking every time adjustments are done.

Am Hoping that a Mac would make things better, but I take it that the collective agreement that it does not make a difference? Is this presumption correct?

I'd say that's what's causing your speed issues. Having ~2500 18mp files open is going to slow your system down. Import a few hundred at a time, or just flag the ones you want to edit and remove the rest from the library for when you want to start editing.

I am running LR3 on all of the following machines right now and have tried RAW post processing on all of them as well and to be honest, as much as I love my Macs, my old, very expensive built (at the time) PC performs much better and I do all my editing on my PC. In fact I have been thinking of rebuilding it the PC with newer higher specs just to get the even more added performance.
