I do a lot ofhow much RAM does ps cs5/6 ext use with CAF?

Question

how much RAM does photoshop cs5 extended use with Content-Aware-Fill?
please state the size of the image, how many layers you have (makes a difference).
please do this for 2 different size images.
I could also use some cs6 numbers as well, since this is the current ps.
should be as simple a psd as possible.
I need to know for a 32-bit and a 64-bit machine.
I would like to use these two numbers for making a calculator that does some very basic calculations as to how much memory would be required to run photoshop given:
image size
content-aware fill
radial blur
number of layers
content-aware move (in CS6)
this means several types  of test plans:
32-bit ps ext CS5:
different image sizes SMALL and LARGE (these sizes will be used throughout the tests below, save them as PSD's)
SMALL and LARGE with 2 layers
SMALL and LARGE with content-aware fill, like taking out a telephone pole. hit F1 if you don't know how.
SMALL and LARGE with radial blur (this takes a while to run). hit F1 if you don't know how or refer to this: http://ksimonian.com/Blog/2010/02/24/improved-photoshop-benchmark-cpu-speed-test-for-both- mac-pc-free-radial-blur-filter-test/
SMALL and LARGE with content-aware fill and then radial blur (this takes a while to run). this step is purely optional.

if you know of a more memory-intensive operation, such as radial blur (maybe that's only cpu-intensive), I would be interested in knowing about this.

the number of layers seem to multiply the RAM required in CS5. I think.  the amount of RAM required to do photoshop seems to be a much-talked about subject and the subject of much variableness, and I wanted to nail it down a little. 
I thought I would make a calculator that can estimate the amount of RAM required for a system to do, say, multilayer gigapixel content-aware-fill stuff in ps, something I know I would do a lot of. I also hear RAM requirements has changed in CS6. it would be interesting to characterize it.
I am making it here: http://Jesusnjim.com/calculators/photoshop-ram-usage.html
and as soon as I can get some completed set of numbers infor CS5 or , it will be ready
you can tell how much memory us in use by doing [windows-logo-flag-key]taskmgr[Enter] or doing ctrl-alt-del and bringing up the task manager,
clicking on the prcesses tab,and looking for Photoshop.exe
if you don't see mem usage, do View,Select columns.
it's a lot of testing, I know, it should not take too long to finish. but I think it might help a lot of folks when they are trying to figure out how to spec their PS box.

the numbers basically would form a linear graph in memory usage when it comes to things like
number of layers
image size
I am not throwing away my data because someone is poo-pooing it.
CAF is just an 11x multiplier in every case I have used it. I am curious what the cs6 new content-[fill-in-the-blank] features use for memory. and I probably can't get anyone else to test it for me, because nobody seems to know how that I have met on the forums except me (I have been doing testing for 27 years and design/development for as long as I can remember - am I getting that old?).
the numbers in these cases are linear, for initial operations (I should qualify that on the page). as you said (according to my numbers), subsequent ops cause increased memory usage. I see this in soundbooth, to the point of out of memory error and crash.
I didn't do graphs because I didn't think it was worth it. I have proved my point to myself.
I think looking back I should have expressed more of what I found (and you guys have just stated it). page editing takes a lot of thought. I guess I missed that 1 necessary thing I noticed and didn't pay enough attention to - ps RAM usage growth from ops doesn't quit until you close it.
found out ps ram usage is not a compendium of all the features (maybe the major ones). the filters use pretty much no noticeable RAM.
adjustments don't either I don't think (haven't tested that).
I just want to help others who are trying to size a new box and don't know how much RAM to get if they are doing a 40x27 poster. and which type of machine: a desktop, laptop, or workstation (which can handle more memory). and which OS (windows 8 handles 512GiB max, windows 7 handles 192GiB max, windows server standard handles multi-terabytes of RAM). why? because I have to size one for myself! and I have some large images I will be working with.
Memory Limits for Windows Releases (Windows)
very few people know about this memory limitation on windows, but it's keenly felt when someone is buying a workstation. microsoft publishes the memory limits on its software for issues like this.
