Registry tweaks related to NT File System (NTFS)
NTFS
has few registry entries which depicts how the file system works and
what things it keeps in mind every time the file structure is accessed.
We can disable few of the features to reduce the 'overhead' and hence
improving the performance. Where we have hundreds and millions of files
to be enumerated, this feature can be an overhead keeping the
performance in mind. Few of them are:
NTFSDisableLastAccessUpdate:
Disables last accessed timestamp of a file. By default NTFS updates the
date and time stamp of the last access on directories whenever it
traverses the directory. Go to the following registry and change the
value to 1. (DISABLE Last Access Update)
Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
NValue name: NtfsDisableLastAccessUpdate
Value Type: REG_DWORD
Value Data: 1
InfoCacheLevel: Enables caching for all files if set 10 (hex).
Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRxSmb\Parameters
Value Name: InfoCacheLevel
Value Data: REG_DWORD
Value Data: 10 (Hexadecimal)
