What is IRPStackSize?

IRPStackSize is a registry value that controls the maximum number of entries in the I/O Request Packet (IRP) stack. The IRPstack is used to process I/O requests sent by applications. When the IRPstack is full, new I/O requests are blocked until existing ones are processed. This can lead to slowdowns and increased latency. To change this registry value you will need administrative rights on your computer. Open up regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk \Parameters . Once there find and double-click IRPStackSize. Change the REG_DWORD under Value data from 4 to 8. Restart your computer for changes to take effect. You should now notice an improvement in network speed when accessing data or performing file transfers.

  2. Once the Registry Editor is open, navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
  3. In the right-hand pane, double-click on IRPStackSize. If the value isn’t there, you can create it by right-clicking on an empty space in the pane and selecting New > DWORD (32-bit) Value.
  4. Enter a value between 1 and 50, depending on how much RAM you have installed on your computer. For example, if you have 8GB of RAM, enter 40.
