TCP/IP Acceleration
Note: Enabling TCP/IP acceleration enhances your network performance but can
cause your network traffic to bypass the firewall because all processes are
off-loaded to the hardware.
NVIDIA TCP/IP Acceleration technology is a networking solution that moves
the processing of TCP/IP network traffic from your computer’s CPU to its
nForce hardware resulting in greatly improved system performance.
NVIDIA TCP/IP Acceleration provides deep levels of networking and traffic
inspections at full-duplex gigabit Ethernet speeds. Overall system performance
is greatly improved because the CPU is not tied up processing network traffic,
especially at gigabit Ethernet speed.
