Increase the FileSystem Memory Cache Size in Vista

I've always wondered why Windows doesn't allow you to set an arbitrary size for the filesystem cache. What if you have a slow hard drive in your laptop,

but loads of available system memory? Shouldn't you be able to maximize that memory in order to speed up hard drive access?

I've found a slightly documented tweak that will allow you to tell Windows to use more cache for the NTFS "pool",

which should increase performance if your system opens and closes a lot of files all the time like mine does.

According to the Microsoft documentation:

Increasing physical memory does not always increase the amount of paged pool memory available to NTFS.

Setting memoryusage to 2 raises the limit of paged pool memory.

This might improve performance if your system is opening and closing many files in the same file set and is not already using large amounts

of system memory for other applications or for cache memory. If your computer is already using large amounts of system memory for other applications

or for cache memory, increasing the limit of NTFS paged and non-paged pool memory reduces the available pool memory for other processes.

This might reduce overall system performance.
