I've not timed the task specifically, but I know I've done case

and a fast disk, and walked out of the room for dinner or
something like that. The job is done when I return to the room,
hmm, about an hour later.
I'd be putting up the 2000x3008 files. Unfortunately, the extra
two hours in your scenario is far too long.
Ok, so you got me interested in timing the process as I haven't done
any practical performance investigation on the G5 so far. I know it's
faster than my iMac G4 20" was, but by how much I could not say
before this.
System: Power Macintosh G5 2Ghz DP, 3G RAM, 500G hard disk, Mac OS X
v10.4.6.
Software: Adobe Photoshop CS2, Bridge and Camera Raw (latest updates
to all).
Procedure:
Collected 100 DNG format RAW files (Pentax, Panasonic and Sony
originals so 6, 8.5 and 10Mpixel mix), copied to a new folder.
Opened the folder in Bridge and let it do its default processing of
the file thumbnails - 2 minutes
Opened all files in Camera Raw.
Set workspace parameters to sRGB, 2008x3008 pixel resolution, JPEG
(quality 10) output.
Selected all files.
Output to full resolution JPEGs took 4 minutes.
That leads me to believe that processing 800 Pentax RAW files to a
full resolution JPEG, using standard parameters, would consume under
40 minutes, give or take, with this setup.
