So now you agree that instead of:
you should have written:
What will happen is that windows pro/windows server will use 4GB for
all applications in total. You will have 4GB of unused memory. The 4GB
ram that is used by windows will have to be shared among those 4
photoshop sessions that want 2GB each.
NO NO NO!!!
What you write contradicts EVERY document from Microsoft!
See the clear explanation from Microsoft that I quoted in the rest of
my reply which you have conveniently not quoted.
The part where I asked you to react to the sentences from Microsoft.
Again Microsoft is very clear about this question:
"Typically, a process running under Windows 2000 or Windows Server
2003 can access up to 2 GB of memory address space (assuming the /3GB
switch was not used) with some of the memory being physical memory and
some being virtual memory. The more programs (and, therefore, more
processes) that run, the more memory you commit up to the full 2 GB of
address space."
What do you not understand in that sentence?
Microsoft clearly states that your applications in total get 2GB
instead of your claim of 4GB.
btw: I'm still waiting for your reply to the questions I had in my
last reply.
