In traditional networking environments, inspecting packets is laborious and
affects CPU overhead, memory bandwidth, and overall system latency. In
comparison, the NVIDIA TCP/IP Acceleration engine discards bad packets
before the CPU detects them. In addition, good packets take an “express lane”
and bypass the traditional “network stack” process, improving overall
throughput and lowering CPU utilization.
T configure TCP/IP acceleration, select
Set TCP/IP Acceleration
configuration from the Networking screen. Note that by default, TCP/IP
acceleration is turned off (the Not be hardware-accelerated radio button is
checked). Click the Use hardware-acceleration (recommended) radio button
to enable TCP/IP acceleration. Click Apply to save changes.
