You can choose between TCP or UDP traffic and set the destination port, bandwidth rate (if UDP is selected), DSCP marking, and TCP window size. Let me start with couple of statements that would explain the issue in broader terms. Chelsio crypto accelerator secures data using. IPsec performance evaluation environment • Evaluate iPerf single-stream throughput and CPU utilization profile for a 10G line on an X5-4, using Intel's ixgbe driver • Test permutations generated with the following parameters - With/Without TSO, GSO, GRO - Clear traffic vs IPsec with null encryption (thus no crypto overhead). – womble ♦ Apr 27 '12 at 15:12. Use this tool to assess the bandwidth available between two computers. Description¶.
