Re: Physical Memory

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."
