Is your media library on the boot drive or on another drive?
Because iPhoto basically has a huge index to its database, the ideal setup would be the index on a very fast SSD, the database files on another drive, and of course a fast boot drive for just the OS.
How full is your boot drive and have you considered moving files off the boot drive? iPhoto, iTunes etc can reside anywhere. Or even use stripe array.
My Media Library is on boot drive, a 500Gb Sata II drive 50MB/s read write capable.
Disc have 250 GB free and IMHO the problem isn't there for more than reasons:
- Leopard has no problems and works like a charm
- The drive has 50Mb/s trasfer rate, for a 10 Mb image is a joke
- During editing of one image, activity monitor reports no significant disc access, only 1 CPU core that rises at 100%
- Issues only when image is >display< big, the image weight is the same on DB, independently the actual screen resolution
- After restoring Leopard, with the same configuration, the problem disappeared
Anyway, after update I've also rebuilt the library without beneficts.
The problem seems to be in graphics management at that resolution, (I suspect the 8800GT not perfectly optimized).
Did you have the chance to try that on your machine (seems you have an GT8000 and a MacPro):
- Snow Leopard
- Screen res of 2560x1600
- Full screen edit of a 15Mpx image
- Do some corrections (the weightiest are, in order, highlights, definition, straighten and sharpness ) on same image
- try to see after/before function (SHIFT key) quickly
On Leopard all those operations are fluids and smoothly, on Snow, like on a G4 :/
