FSUtil performs tasks that are related to file systems, such as managing reparse points, managing sparse files, or dismounting a volume. You can also get a bit of a speed boost with it.

By default, Windows will use a percentage of your system memory as internal cache for NTFS, or file system operations. You can increase the size of this cache, thereby resulting in fewer trips out to the slower hard disk drive, thus increasing performance.

Note, if you have less than 2GB of RAM, it is not recommended you try this.

  1. Click the Start orb, and type CMD in the search box.
  2. Right-click the CMD.EXE entry, and select Run As Administrator
  3. In the command prompt, type the following command, then press enter:fsutil behavior set memoryusage 2
  4. Reboot your computer for the settings to take effect.

If you'd like to reset the value to the default setting, replace the 2 with a 1 in the above example.

Configures the internal cache levels of NTFS paged-pool memory and NTFS nonpaged-pool memory. Set to 1 or 2. When set to 1 (the default), NTFS uses the default amount of paged-pool memory. When set to 2, NTFS increases the size of its lookaside lists and memory thresholds. (A lookaside list is a pool of fixed-size memory buffers that the kernel and device drivers create as private memory caches for file system operations, such as reading a file.)
