Re: Physical Memory

Not to walk over Daave, but in his reply to me he mentioned that there would
be processes running in the background. I have replied to him that there are
zillions of them. It seems to me that your explanation to me must apply to
these processes, because after all they are also programs.

So the question that comes to my mind is whether these processes are all
necesesary. Is it possible that some might be associated with applications I
no longer have? Or that they have been installed without my knowledge off the
Internet? Is there a way I can find out and get rid of the unnecessary ones?

I thhought db was suggesting ways I could do this, but apparently what he
was suggesting was going to do something else.

Certainly my computer has become much slower than it used to be. I have a
3.0 gig Pentium 4 processor and apparently a half gig of available memory,
but it takes forever to load Microsoft Word, say, or AOL.

Don't listen to that db character and don't use that crap that he
recommends. Memory optimizers/defragers are nothing more than snake
oil, they provide absolutely no useful benefit to the memory management
of your Windows installation, quite to the contrary they create havoc
and force disk paging in order to create an illusion that they have
freed memory!

These optimizers work by making demands on the Windows Memory Manager
for a rapidly and steeply increasing amount of memory to the point where
the Windows Memory Manager pushes all the pageable code and data to the
pagefile to satisfy the demand. Once the code and data for all the
other applications (the Working Sets) has been paged out the snake oil
program then tells the Windows Memory Manager that it no longer needs
the memory that it asked for and it releases it, this creates an
illusion that memory has appeared out of nowheres.

The only problem with that is that all the other applications and
pageable system processes are now in the pagefile and that anything that
you do that needs the paged out code and data takes an eternity to run
because it has to get it from the pagefile, in many instances some
applications will simply crash! Things like using your web browser's
"Back" button to go to a previous page or reopening a Word document that
you had open only 30 seconds ago will now take forever! Even certain
Windows functions will lag and be sluggish.

The funny thing about all of this nonsense is that the snake oil memory
optimizer cannot do anything on its own, like all other applications and
processes it cannot manage memory at all, the Windows Memory Manager
does *absolutely* not permit this, all that the rogue application can do
is ask the Windows Memory Manager for RAM and then close the process
demanding the RAM or have the process "unallocate" the RAM. Yet even
more of a silly thing is that if you open an application, like lets say
Word, it will ask for a certain amount of RAM and the Windows Memory
Manager will comply, just as it did for the snake oil, and if needed it
will page out code and data just as it did for the snake oil. Once your
Word program is up and running if you want to open documents the same
thing happens all over again. The difference is that the Windows Memory
Manager will do this in a measured orderly manner as demanded by the
properly designed application instead of in a completely reckless manner
as demanded from a rogue snake oil program!

System information on my XP PC tells me I have total physical memory of 1,024.00 MB, and Available physical memory of 491.98 MB.
Does this sound right? Why the discrepancy?



What discrepancy? Naturally, if your computer is powered on, some of its memory will be in use, and therefore not "available."
