![]() We note that generic segmentation, TCP segmentation and generic receive functions are offloaded to the LAN card. To see what functions are offloaded to the LAN card use ethtool: This can provide a performance improvement in that the segmentation is performed in hardware by the LAN card as opposed to in software by the OS. The operating system can offload TCP/IP functionality, in particular segmentation of packets, to the LAN card. Offloading TCP/IP Functionality to the LAN Card Read on for explanations of each step and the final results. ![]() the -w option, also changing the RTT (step 5) when needed. Repeat the iperf tests with different values of the receive buffer, i.e.Use iperf to measure the TCP throughput for varying BDP and receive buffer sizes, e.g. ![]()
