Windows Xp Memory

Hi,

I am developing a very memory intensive application in ASP.NET and I have a
question regarding how Windows XP manages memory allocation.

I currently have Windows Task manager open on the Performance tab and it is
showing that I am using 684MB of the 1GB Ram I have installed in this
machine.

However if change to the Processes tab and add up the Mem Usage of every
process currently running, the value I get is around 250MB.

I was hoping you might be able to shed some light as to what the rest of the
684MB is being used by...

Many Thanks,

Jim
 
First of all, in task manager, make sue you tick the box "show process of
all users". ASP.NET applications under IIS run under a different account
than the logged on user.

Next, you do not use 684 MB of the 1 GB installed, you are using 684 MB in
total of the total memory that Windows can access. So that is RAM and the
page file. Which should be an extra 1~2 GB depending on how you configured
that. Quite a lot of processes are moved to the memory space of the page
file since they do not need that frequent accessing.

If you have a webapplication using this much memory per user under IIS, I
would not consider to release it to the outer world by the way...you would
need quite a serverpark to host that for multiple users.
