RAM allocation with 8GB
I have 8GB of RAM. I have set the memory usage in CS3 to 100% 3255 GB. Is this correct? I can't make sense of the Adobe recommendations, which seems
to suggest that I should set it to less than this even with 8GB of RAM.

If your on a Mac the sorry you can't go higher than that 
I have a MacIntel with 16GB waiting for that time to come 
On the PC its practically the same but not sure if Windows xp64 can?

If your on XP it can only see up to 4GB without some modifications. Although higher ram (at some point) won't be the bottlekneck. Get a 2nd hard
drive, make it a physical scratch disk and disable background processes on your machine.. you will see better performance.

Maybe a bit of a late reply, but then again, I just joined so...
Ayway; mkeefe is right on both accounts. That's to say, Win XP and Vista 32 Bit can only see a maximum of 4GB of system memory. XP and Vista 64 Bit
can see 8GB.
Usually, when installing 4GB of memory in a 32 Bit system, Windows will not show the full wack, but depending upon the amount of memory your VGA card
has, and the amount of PCI cards in your system, you will see anything from 3 to 3.5GB of memory. This is because add on cards will take up their
equivalent of onboard memory for kernel operations. Likewise, Windows, by default, also allocates part of the system memory for kernel operations.
So here is a rundown of what I suspect that is happening with your system dave w:
1: Although you have 8GB of RAM installed, your system is only seeing 4GB because you're running a 32 Bit OS.
2: 4GB minus all the memory that is needed for kerel operations y the add-on cards means Windows will only show you that it has 3.5GB of RAM
installed.
3: In this case, PS is probably showing you that the recommended limit of system RAM for PS operations is something of around 1.8 to 2GB. It is so
clever enough to know that a big chunk needs to be kept available for Windows kernel operations.
By specifying PS to use the full 3.5GB of system RAM, you'll most likely create the averse effect of what you're trying to achieve because you're
forcing Windows to use the page-file (= virtual memory) for all it's operations.
I would set the memory allocation in PS back to what is recommended. As mkeefe suggested, you could get a second physical harddrive in your system to
use as the PS scratch disk. Although, out of experience, I have found that it is etter to move the Windows page-file to a different system disk
first.
Sorry for the long reply, although I do hope it solves your problem though.

@Desertfish - When i was on a PC I moved the paging and indexing storage to a new drive, and my god, the performance increase on day-to-day, as well
as searching was amazing.
