4 TRex performance test results are reported for a range of processors.
5 For description of physical testbeds used for TRex performance tests
6 please refer to :ref:`tested_physical_topologies`.
11 CSIT TRex performance tests are executed on physical testbeds described
12 in :ref:`tested_physical_topologies`. Logical topology use 1 nic that has
13 loopback connected ports. See figure below.

33 Performance Tests Coverage
34 --------------------------
36 Performance tests measure following metrics for tested TRex
37 topologies and configurations:
39 - Packet Throughput: measured in accordance with :rfc:`2544`, using
40 FD.io CSIT Multiple Loss Ratio search (MLRsearch), an optimized binary
41 search algorithm, producing throughput at different Packet Loss Ratio
44 - Non Drop Rate (NDR): packet throughput at PLR=0%.
45 - Partial Drop Rate (PDR): packet throughput at PLR=0.5%.
47 - Two-way Packet Latency: measured both east-west and west-east at different
50 - 90% of discovered PDR throughput.
51 - 50% of discovered PDR throughput.
52 - 10% of discovered PDR throughput.
53 - Minimal offered load.
55 |csit-release| includes tests using the following TRex traffic profiles
56 (corresponding to data plane functionality when DUT is used)
57 performance tested across a range of NIC drivers and NIC models:
59 +-----------------------+----------------------------------------------+
60 | Traffic profile | Corresponding dataplane functionality |
61 +=======================+==============================================+
62 | IPv4 Base | IPv4 routing. |
63 +-----------------------+----------------------------------------------+
64 | IPv4 Scale | IPv4 routing with 2M entries. |
65 +-----------------------+----------------------------------------------+
66 | IPv6 Base | IPv6 routing. |
67 +-----------------------+----------------------------------------------+
68 | IPv6 Scale | IPv6 routing with 2M entries. |
69 +-----------------------+----------------------------------------------+
70 | L2BD Scale | L2 Bridge-Domain switching of untagged |
71 | | Ethernet frames. |
72 +-----------------------+----------------------------------------------+
75 Performance Tests Naming
76 ------------------------
78 FD.io |csit-release| follows a common structured naming convention for
79 all performance and system functional tests, introduced in CSIT-17.01.
81 The naming should be intuitive for majority of the tests. Complete
82 description of FD.io CSIT test naming convention is provided on
83 :ref:`csit_test_naming`.
