This section describes various latency tests.
X4 series network adapters use cut through PIO (CTPIO) on their Express datapath. Packets to be sent are streamed directly over the PCIe bus to the network port, bypassing the main adapter transmit datapath. For more information refer to CTPIO.
The command lines given below use the taskset command to run the tests on core 1. Change this as necessary, to
use an appropriate isolated core on your test system.
