How to Adjust NTFS Memory Allocation in Windows

NTFS caches the files that are open in physical memory for the fastest possible access to the raw data. It does this by first reading the data from the hard drive and then transferring it to physical memory. Depending on the amount of RAM in your computer, portions of the open files may be paged to disk in the paging file because the entire file cannot fit in the available physical memory.

The file system allocates only a certain amount of physical and paging file space, which results in increased paging activity and slow down of your file access time. Depending on the amount of physical memory in your computer, you might be able to get away with increasing the memory allocated to NTFS on your computer. This will increase the performance of high disk read operations if you have enough free RAM in your PC.


Follow these steps to increase the memory available to the file system:

1. Open the Command Prompt by clicking Start Menu --> All Programs --> Accessories, right-click on Command Prompt, and open it as an administrator. In Windows 8, 8.1 and Windows 10 type cmd.exe into Start Screen or Start Menu, right-click on Cmd.exe, and open it as an administrator.

2. Execute following command:

Code:

fsutil behavior set memoryusage 2

3. Close Command Prompt and restart your computer to activate the change.

If you notice any decrease in performance or have bad results from this tweak, undoing the change is very simple. Just type fsutil behavior set memoryusage 1 at the prompt instead and reboot.
