Windows performance for uploading packages

When you upload packages from a Windows computer, users can improve the performance of the computer used to upload by changing TCP stack registry settings that affect upload speeds. The recommended change to the Windows registry file increases the default tcp-send buffer size from 8 KB to 16 KB.

Consult your system administrator before you make this change.

Perform the following steps to change the tcp-send buffer setting:

  1. Using regedit, navigate to the following registry key:

    HKEY_LOCAL_MACHINE
    SYSTEM
    CurrentControlSet
    Services
    Afd
    Parameters (Create this key if it does not already exist)
  2. Set the following value for the key:
    Name: DefaultSendWindow
    Value Type: REG_DWORD
    Value: 16384 (decimal)

After you set the value, reboot the machine for the changes to take effect.
