File system cache size. How to increase it?

[Sergey via WindowsKB.com]

I have an application that reads data from a 2 GB file. Is there any way to
increase the file system cache size, and make Windows keep most of data in
RAM (I have more than 3GB unused RAM)?

Go to run,type:regedit In regedit expand:HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\SessionManager\ then open MemoryManagement.
You'll find and L.click LargeSystemCache Go to edit,modify,set to 1 from 0
You can also L.click DisablePagingExecutive Set to 1 from 0 This increases
paging of the NT Executive to ram instead of the page file.Once thru,close
out restart computer.

LargeSystemCache is already set to 1 on my computer.

You can also L.click DisablePagingExecutive Set to 1 from 0 This increases
paging of the NT Executive to ram instead of the page file.Once thru,close
out restart computer.

I am not sure I need it as I do not have a big executive file. I just have a
couple of huge readonly data files.

loose /3GB if you have it in your boot.ini
change LargeSystemCache back to 0 - this is a Workstation, right? Not File
Server with static workload.

You (and everyone else) don't need DisablePagingExecutive set to 1 - it
affects _only_ Ntoskrnl.exe and nothing else. And all it does - keeps couple
megabyte of code in RAM, no matter how long ago it was touched - doesn't
affect performance in slightest - this setting was designed for
troubleshooting only.
