| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0x0 - 0xFFFFFFFF bytes | 0x19000 (102,400) |
Specifies the maximum amount of system memory that a device driver is permitted to allocate to its fast forwarding cache. The fast forwarding cache is a section of reserved memory used to support TCP/IP fast forwarding.
This entry is used only when fast forwarding is enabled (that is, the value of FFPControlFlags is 1) and the driver uses system memory for its cache. This value does not apply when the driver uses memory on the device for its cache.
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
