Hi!
Hard disk speed and layout is responsible for a good part of how long it
takes to make a conversion. A separate, dedicated HD for the PS scratch
disk is highly recommended. My program files are on a separate partition,
as is the Windows Paging File, and the working files are on another drive.
Lots of free contiguous space (i.e., an unfragmented disk) is another
important consideration.
That's right. I have a dedicated partition to PS scratch files... Also I
have two hard drives...
Another factor is how you've set up Photoshop to use memory, what programs
and services are running in the background, and how well you've optimized
Photoshop to run in your individual environment.
Using Win XP Home with a 2.8GHz processor and 2GB ram with 60% allocated to
Photoshop, the average conversion time from a 9+mb RAW file to a 16-bit PSD
on my machine is 4.3 seconds based on Photoshop's timing.
I allow PS to take 85% of my RAM... The amount of other stuff running at
the same time is minimal.
