Prevent superfetch from caching files in ram disk!

[paradis pal]

Hi again!

I have noticed that the files in the Ramdisk will be cached in ram by the service superfetch . Although it is in the priority 2 but it just will use more resources to duplicate the file in the RAM again.

Is there anyway to prevent ram-disk from being cached into windows superfetch service?

The only known option for superfetch are using registry:

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

EnablePrefetcher=

Disable Caching: 0
Cache Applications Only: 1
Cache Boot Files Only: 2
Cache Everything (default): 3

I know no way for a specific volume to be ignored by this service.
But even with this service disabled, files are still cached by the system, like for any volume. It would be nice to disable this behavior which is useless for a ramdisk but there too, I don't know whether it is possible.
