Added Testpmd tests - - - new NICs - Intel x520 - -Multi-Thread and Multi-Core Measurements ----------------------------------------- - -**HyperThreading** - CSIT |release| performance tests are executed with SUT -servers' Intel XEON CPUs configured in HyperThreading Disabled mode (BIOS -settings). This is the simplest configuration used to establish baseline -single-thread single-core SW packet processing and forwarding performance. -Subsequent releases of CSIT will add performance tests with Intel -HyperThreading Enabled (requires BIOS settings change and hard reboot). - -**Multi-core Test** - CSIT |release| multi-core tests are executed in the -following Testpmd thread and core configurations: - -#. 1t1c - 1 Testpmd pmd thread on 1 CPU physical core. -#. 2t2c - 2 Testpmd pmd threads on 2 CPU physical cores. -#. 4t4c - 4 Testpmd pmd threads on 4 CPU physical cores. - -Note that in many tests running Testpmd reaches tested NIC I/O bandwidth -or packets-per-second limit. - -Packet Throughput Measurements ------------------------------- - -Following values are measured and reported for packet throughput tests: - -- NDR binary search per RFC2544: - - - Packet rate: "RATE: <aggregate packet rate in packets-per-second> pps - (2x <per direction packets-per-second>)" - - Aggregate bandwidth: "BANDWIDTH: <aggregate bandwidth in Gigabits per - second> Gbps (untagged)" - -- PDR binary search per RFC2544: - - - Packet rate: "RATE: <aggregate packet rate in packets-per-second> pps (2x - <per direction packets-per-second>)" - - Aggregate bandwidth: "BANDWIDTH: <aggregate bandwidth in Gigabits per - second> Gbps (untagged)" - - Packet loss tolerance: "LOSS_ACCEPTANCE <accepted percentage of packets - lost at PDR rate>"" - -- NDR and PDR are measured for the following L2 frame sizes: - - - IPv4: 64B, 1518B, 9000B. - - -Packet Latency Measurements ---------------------------- - -TRex Traffic Generator (TG) is used for measuring latency of Testpmd DUTs. -Reported latency values are measured using following methodology: - -- Latency tests are performed at 10%, 50% of discovered NDR rate (non drop rate) - for each NDR throughput test and packet size (except IMIX). -- TG sends dedicated latency streams, one per direction, each at the rate of - 10kpps at the prescribed packet size; these are sent in addition to the main - load streams. -- TG reports min/avg/max latency values per stream direction, hence two sets - of latency values are reported per test case; future release of TRex is - expected to report latency percentiles. -- Reported latency values are aggregate across two SUTs due to three node - topology used for all performance tests; for per SUT latency, reported value - should be divided by two. -- 1usec is the measurement accuracy advertised by TRex TG for the setup used in - FD.io labs used by CSIT project. -- TRex setup introduces an always-on error of about 2*2usec per latency flow - - additonal Tx/Rx interface latency induced by TRex SW writing and reading - packet timestamps on CPU cores without HW acceleration on NICs closer to the - interface line. - - -Report Addendum Tests - Additional NICs ---------------------------------------- - -Adding test cases with more NIC types. Once the results become available, they -will be published as an addendum to the current version of CSIT |release| -report. |
