Continuous Mode Performance =========================== This is the test plan for unit test to measure cycles/packet in NIC loopback mode. This section explains how to run the unit tests for pmd performance with continues stream control mode. The test can be launched independently using the command line interface. This test is implemented as a linuxapp environment application. The final output of the test will be average cycles of IO used per packet. Burst Mode Performance ====================== This is the test plan for unit test to measure cycles/packet in NIC loopback mode. This section explains how to run the unit tests for pmd performance with burst stream control mode. For get accurate scalar fast performance, need disable INC_VECTOR in configuration file first. The test can be launched independently using the command line interface. This test is implemented as a linuxapp environment application. The final output of the test will be matrix of average cycles of IO used per packet. +--------+------+--------+--------+ | Mode | rxtx | rxonly | txonly | +========+======+========+========+ | vector | 58 | 34 | 23 | +--------+------+--------+--------+ | scalar | 89 | 51 | 38 | +--------+------+--------+--------+ | full | 73 | 31 | 42 | +--------+------+--------+--------+ | hybrid | 59 | 35 | 23 | +--------+------+--------+--------+
