Increase AFD Buffer

Modifying your registry can cause serious problems. Please make a restore point or export the keys affected by these registry files. The batch files export the registry keys for you and are placed in My Documents under RegBackup.

If you are not sure how to export or merge registry keys, I have written a quick tutorial.

This registry patch increases the AFD buffer from 512 to 1024. Increasing this value increases the number of messages sent before flow control is imposed. This increases throughput.

None really, if you want to undo it, just use the undo file.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
"BufferMultiplier"=dword:00000400

1. IncreaseBuffer.bat
2. IncreaseBuffer.reg
3. UNDO_IncreaseBuffer.reg

Save #1 to your desktop, double-click the batch file, the affected registry key will be exported for you, and the registry file will be merged.

Usually your computer must be restarted for these to take effect.

The UNDO file 3. is needed to undo this change.
