Bad memory utilization in Windows XP x64

[amirjadidi]

Hi,

I have Intel corei7 + 12GB of memory. When I'm using ubuntu 9.04 application are effectively cache into memory for future runs. But I have problems in Windows XP!

XP just use 2GB of memory and when I switch between different application, it takes a long time to load them again. It's really bad behavior for daily usage.

After some googling I found that there are some tweak to solve this problems (Refer to "Tweak #4: Kernel Paging and Cache Tuning"). I changed the following:

Part 1: DisablePagingExecutive

Part 2: Enable LargeSystemCache

But It doesn't work (2GB is maximum usage!).

How can I tune my machine in order to have better memory utilization?

Hi, welcome to the forum.

Read their section again (caveats). Don't use LargeSystemCache if the machine is not a server (serving files).

I don't have conclusive opinion about DisablePagingExecutive. I haven't noticed much difference on any machines I've tried.

But I suspect your issues (or expectations ) are something completely different:

1. Prefetch

2. PAE

Read/investigate on these. I hope someone more knowledgeable than me in these areas will answer.
