Solve : core system?

Answer»

Hello


   I run across a xp tip about keeping core system in memory the instructions to do so are below. I just WANTED to run this by you fine folks before i started messing around in my registry.
Will this help performance any?
thanks

Launch the Registry Editor (Regedit.exe).
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Session Manager\Memory Management.
Double-click DisablePagingExecutive DWORD value.
Change the value in the Value Data text box from 0 to 1, and click OK.
Close the Registry EditorIt might degrade performance in some instances by increasing the Non-Paged-Area of ram, denying the use of some ram which is not being used at any given TIME, decreasing the size of the Page-Pool.  This could mean that when gaming, for example, much more use would have to be made of the hard drive page file.   I would expect the impact to be greater if total ram was <= 256mb than if it was say 2gb.

Maybe you'd like to do a before-and-after comparison and post the results.

My researches suggest that there would be an impact, sure, but not a good one. Only users with 256MB+ should use this setting, it is widely stated.

User-mode and kernel-mode drivers and kernel-mode system code are usually written to be either pageable or non-pageable. In cases where drivers or system code is pageable, you can disable the paging executive to keep this pageable code in RAM, but this is only said to be advisable on systems with larger amounts of RAM.

If your system has enough physical memory, performance will increase if the operating system does not page itself to disk. The best way to make sure is to load all of your applications and use the task manager (press Control-Alt-Delete) and click the performance tab. Your physical RAM should be greater than the Peak Commit Charge by at least 16MB.

My system has 1GB and my peak commit charge today so far is 388 MB. I have Firefox, Xnews, Azureus, and 5 small apps like Notepad running. I am going to give it a try.


I've heard that this isn't recommended for anyone with less than 1gb ram. I did use this tweak for some time but stopped because I didn't feel any improvement in performance.When Windows XP was RELEASED in 2001, 256 MB was a common amount of RAM for a well specified system. When it was being written and beta tested, that was a LOT, or at the large side of a normal amount. It is interesting to see how vague and imprecise some web articles can be. When I was Googling for information about this topic, I kept finding remarks suggesting that the tweak should not be done unless the system has a "very large" or even "enormous" amount of RAM installed. Pursuing this topic further, I found that in 2001 or 2002 "enormous" seemed to mean "more than 256 MB".

You would think that web pundits would recall (a) the INFAMOUS 1981 remark "no-one will ever need more that 640K of RAM" attributed to Bill Gates, and (b) Moore's Law, and word their pronouncements accordingly.
