Hi everyone,
I have been through a relatively thorough re-configuration of my Mac Pro, specifically looking for optimal LR3 performance with large Raw files (@60-80MB). The computer is a 2.93 quad core Mac Pro with 16GB RAM. To date this has involved installing 2 Raided SSDs (Raid 0) for the OS and applications, and four 2TB drives (Raid 0) - which are partitioned to give a fast 'scratch' volume outside a big 'data' volume. I have also made a fresh (leaner) installation of the OS and all applications.
So, I have the application (LR3) on the Boot, the LR catalogue and all of my Raw files on the Raided (0) Data drive, the LR Cache on the fast (Raid 0) scratch drive, and i am still waiting an age for 1:1 previews to build at just 5 per minute. Worse still (bearing in mind that previews only have to be built once) - switching from one image to the next in Develop module, still takes quite a while (6-7 seconds per image), so editing large numbers of images, zooming in to check critical focus etc, becomes a really slow chore.
The specific reason for posting is to find out if there is something specific that can be done to:
[1] speed up building 1:1 previews?
[2] Speed up file handling when moving between images in the Develop module?
or [3] if i am unrealistic in expecting LR3 to work faster?
And finally...
[4] are the preview files deleted when raw images are deleted from within lightroom?
[5] and if i started the process by simply generating 'standard' previews on import, and then later generate 1:1 previews after i have deleted all unwanted files, will the newer 1:1 preview replace the initial standard preview?
As data accumulates... i am getting more interested in keeping everything as lean (and fast) as it can be...
Thanks for any help,
Scott
