Improve Network Speed in Windows by Increasing IRPStackSize

Last Updated on July 18, 2023

The I/O Request Packet Stack Size (IRPStackSize) is a registry setting that can affect network performance. A larger IRPStackSize value can improve network performance by allowing the computer to handle more data simultaneously.

To increase the IRPStackSize value, you need to edit the Windows registry. Here are the steps:

  1. Open the Registry Editor.
  2. Navigate to the following key:
  1. Right-click the Parameters folder (or right-click an open area in the right-hand windowpane) and select New | DWORD (32-bit) Value from the context menu.
  2. Give the new key entry the name IRPStackSize.
  3. Double-click the new IRPStackSize key you just made and change the value base to Decimal and change the Data value to 32.
  4. Click OK to save your changes.

After you have made these changes, you need to restart your computer for them to take effect.

Note: The IRPStackSize value is a system-wide setting, so it will affect all network connections on your computer.

How much can I expect to improve my network speed?

The amount of improvement you see in your network speed will depend on a number of factors, including your hardware, your network configuration, and the type of traffic you are using. In general, you can expect to see a small improvement in your network speed after increasing the IRPStackSize value.
