![]() ![]() 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 apps or for cache memory. Setting memoryusage to 2 raises the limit of paged pool memory. Increasing the physical memory doesn't always increase the amount of paged pool memory available to NTFS. The disablelastaccess parameter can affect programs such as Backup and Remote Storage, which rely on this feature. If NTFS updates other file attributes such as Last Modify Time, and a Last Access Time update is pending, NTFS updates Last Access Time with the other updates without additional performance impact. One hour is the maximum amount of time that NTFS can defer updating Last Access Time on disk. NTFS returns the correct value on queries because the accurate value is stored in memory. This parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisableLastAccessUpdate registry key.įile-based Last Access Time queries are accurate even if all on-disk values aren't current. Disabling the Last Access Time feature improves the speed of file and directory access. The disablelastaccess parameter reduces the impact of logging updates to the Last Access Time stamp on files and directories. The allowextchar parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsAllowExtendedCharacterIn8dot3Name registry key. This parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation registry key. When NTFS creates files in a directory, it must look up the 8.3 character-length file names that are associated with the long file names. When disable8dot3 is set to 0, every time you create a file with a long file name, NTFS creates a second file entry that has an 8.3 character-length file name. If the average file size on the volume is 1 KB or less, it can be beneficial to set the mftzone value to 4. If the average file size on the volume is 2 KB or less, it can be beneficial to set the mftzone value to 2. The MFT Zone is a reserved area that enables the master file table (MFT) to expand as needed to prevent MFT fragmentation. Doesn't require any service restart when you enable or disable trim.Existing inflight IO are not impacted by the registry change.Trim is effective when the next unmap command is issued.Enabling or disabling doesn't require a restart.If your hard disk drive or SAN reports that it doesn't support trim, then your hard disk drive and SANs don't get trim notifications.For systems using NTFS, trim is enabled by default unless an administrator disables it.For systems using ReFS v1, trim is enabled by default.For systems using ReFS v2, trim is disabled by default.Delete notifications (also known as trim or unmap) is a feature that notifies the underlying storage device of clusters that have been freed due to a file delete operation.
