i am still trying to find the option within xp to load on boot all core operations into memory so to make windows faster.

you have to have more than 512mb to do this but i cant find the option again.

anyones help would be great

Hi Chris,

Its just a guess..

If you succeed then help others

I did this awhile back for Windows 2000, and it worked great with 512Mb of RAM. I had a link to the FAQ (coincidentally, here in tek-tips.com) but it doesn't work anymore for some reason. It used to be located here:

http://www.tek-tips.com/gfaqs.cfm/lev2/67/lev3/70/spid/616/sfid/971

but it goes back to the main page. Anyway, I found this link:

http://www.windows2000faq.com/Articles/Index.cfm?ArticleID=14506

It's meant for NT 4.0, but I think this actually works for 2k as well. XP is pretty much the same as 2K, so it should work as well.

I know the option is in one of the tweak programs i use. I think it's in tweak xp.

. Anyways, im pretty sure it's in that one somewhere, if not it can probably be found in some of the other ones. Im 99% sure it's that one but im on an NT machine here, and wont get home to check until later. ( P.S. It also contains the option to make an xp ram drive if anyone wants one )

hi there mikecx

thanks for that i think you could be right but i have loaded tweakxp but cant see it there but there is a pro version of tweakxp but as far as i am concerned i havent brought one, but i will keep on searching.

if in the mean time you find out where it is i would be most grateful if you would let me know. cheers

You could just tell windows not to use a page file at all. This would prevent anything from paging to disk. This optoin is found in the system properties->Advanced Tab->Performance Settings->Advanced Tab->Virtual Memory Change->No paging file. I know this is probably not what you are looking for, but what the heck!

I am currently running Win XP Professional using an Athlon XP 1900 and 512 MB PC2100 DDR memory (self-built system). I have disabled the swap file completely and have experienced no slowdown or other degredation in performance.

hi all

yes i have diasbled the swap drive but i think the system still goes to the disk to retrieve data for the system files of some sort. i am still looking for this option and when i find it i will shoput eurika!!

thanks for everybodys time

If you are talking about the XP kernel files then you want the to edit the registry as explained by XYRX previously. This edit tell XP to hold the entire kernel in memory. It won't page any system files if you do this. Here is the path just in case you wanted it:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\DisablePagingExecutive

Set the decimal value to "1"

Another good optimization tip is changing the "SecondLevelDataCache" Value to match the amount of L2 cache on your processor. By default XP is set for 256 kb, if you have more you might as well use it!! When changing this value add it as a decimal value in Kilobytes.

I follwed Mortamers instructions and looked at the cache value in the registry. It was set to 0. So's I ran CPUCheck and it tells me I got no cache on the processor. I'm feeling suspicious.

I'm using a dell gx240 with a 1.8 P4. Could this be correct info on the cache level?

 

[Mortamer]

Definitly not 0. The P4's all have at least 256, and yours should be 512. The BIOS on your 240 will tell you the L2 cache size.
