Re: Why I am Limited to about 35 Open Windows With 3GB Ram in New

Tech-Archive recommends: Fix windows errors by optimizing your registry

Mak,

When I used the command prompt to try to start more IE7 windows using "start
iexplore", I got the same effect, could not open any more windows than if I
tried to start IE7 by double clicking on the IE icon on the desktop.

I tried creating the graphs that you suggested in performance, and I think I
did it correctly. I only needed to set the max scale to 1600 instead of
10000. The Handle Count curve was a horizontal line at about 1400. the
Working Set curve was a horizontal line at about 560. The Virtual Bytes
curve was a horizontal line at about 170. The % Processor Time curve varied
with time up to about a max value of 54. The Pages/sec curve was at zero
most of the time.

There is a lot that I don't understand about all this. I think I understand
Processor Time, but that is about it. I am an aerospace engineer, so use
computers a lot, but have not been trained in any of these details. It is
great to learn about anything that helps me use computers more efficiently,
and about computers in general.

Let me know if I am doing something wrong or if you have any other
questions, etc. Perhaps I need to do this differently, or perhaps there
something else I need to check.

Regards,

John

oh, forgot to mention.... if you're not up to session limit, but only per
process, you can start separate IE process from command prompt via:
"start
iexplore" command.

John, you might be running out of GDI Handles.

AFAIK in Xp it's set by default to 10,000 per process. (I've checked
mine
and it's set to 10,000, though I don't remember if I modified that or
not)
You can fire up permon, object 'process' | counter 'handle count' |
process 'iexplore' and watch it rise... check the number after wich you
can't open tabs anymore.
Also, system wide the number of hadles per session is limited to about
65k
(theoretical limit I think).
Total system wide number of handles is also displayed in Task Manager.

I have a 6 month old Dell dual-processor Windows XP desktop PC that is
very
fast. I have Windows XP Media Edition with Service Pack 2. I noticed
I
was
limited to about 35 open windows (for example 35 IE7 windows - not
using
the
tab option in IE7) before apparently running out of memory when I had
just
1GB of memory in the machine. I am working on many things at once and
would
like to be able to open at least 50 windows on the machine.

I just added 2GB of memory (3GB total now) and although the computer
recognizes the extra memory, I can not open any additional windows.
Is
there
some limitation in Windows XP on the maximum number of windows or
applications you can have open, or is there perhaps something wrong
with
the
memory that I installed? I call the memory manufacturer, and they
said
they
memory should be fine and that it is the correct memory for my
machine.
I
called Dell technical support and they don't have any clues. All
inputs
I
received suggest going from 1GB Ram to 3GB Ram should allow me to have
a
lot
more windows open than I had before.

I suspect there is either a limitation in Windows XP or some setting
that
I
need to change to allow it to make use of the additional memory that I
have.
Otherwise it must be bad memory, or something wrong with other
hardware
components.

Thanks in advance for any help or comments on this problem.

Vista likes memory. It will run on lower amounts, but is happy with more.
I am running with 1 GB which is just fine, and it will run on less. Those
running 2GB see very nice performance. I'm on a P4 with 2.53 Ghz. So if
you can afford the memory it's worth it for Vista.
