I installed this program,
and ran programs that require 40 or more 6.13gb images open at the same
time
With the XP_PageFileMon program running it significantly
slowed my computer processing time
In addition I noticed
that when I had AB open to a stock it took a few seconds for today’s
price to come up on the candle-stick chart.
To me this program did
not make things better it made things much worse
Just what I found with my
computer configuration and programs

I have seen some articles claiming that
for large amount of RAM page file should not be increased.
(with very large RAM size you do not need to use any page file at all).
Excessive page file actually
has a negative effect on performance (searching vast size of empty file takes
longer).
There is a tiny freeware utility called
XP Page File Monitor ( XP_PageFileMon.zip circa 2003)
that you should be able to find, it runs as a shut down script.
Once installed, it monitors your actual
usage of page file and writes it to file on all windows shut downs.
You will be surprised at the results.
I have 2GB RAM and set the page file to
2GB which is about 4 times the maximum I ever saw during
2 months of monitoring.

Yep, not your installed memory. I have 1.5Gb and AB
runs fine.
Just a thought... Try turning Off the code switch and then
turning off HyperThreading (I think that's an option), then turn off both.
Also, have you checked your page file size? At 2Gb of memory, it
should be set to about 3Gb.
I can't think of anything else.

2gb of memory, think it is
like 533 speed, Hyper thread machine, plus I changed the Microsoft
code switch to allow 3gb of memory and page memory is maxed out too
That is not the
issue, has to do with settings inside AB I would think

AB and eSignal are memory "intensive". With EOD
data (i.e., no live datafeed), I've had AB use more than 1/2 Gb of memory after
an exploration.
How much memory does your system have? If less than 1Gb, consider
upgrading.

I am trying to run an explore on my
whole data base now and am getting an out of memory though it says
E-signal out of memory and AB is
locked up
Any suggestion?
Thank you
Mark
