VPP performance test environment changes +#. Added VPP performance tests - - Further optimizations of VM and vhost-user test environment - various - Qemu virtio queue size testing with value of 256 and 1024. Applied - Linux CFS optimization to run VPP worker threads and Qemu worker threads - with highest priority. + - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif** -#. VPP performance test framework changes + - Added tests with VPP vswitch in container connecting a number of VPP- + in-container service chain topologies with L2 Cross-Connect and L2 + Bridge-Domain configurations, orchestrated by Kubernetes. Added + following forwarding topologies: i) "Parallel" with packets flowing from + NIC via VPP to container and back to VPP and NIC; ii) "Chained" (a.k.a. + "Snake") with packets flowing via VPP to container, back to VPP, to next + container, back to VPP and so on until the last container in a chain, + then back to VPP and NIC; iii) "Horizontal" with packets flowing via VPP + to container, then via "horizontal" memif to next container, and so on + until the last container, then back to VPP and NIC; - - Full code review, optimization and refactor. + - **VPP TCP/IP stack** -#. T-rex changes + - Added tests for VPP TCP/IP stack using VPP built-in HTTP server. + WRK traffic generator is used as a client-side; - - Full refactor of T-rex driver and introduce of traffic profiles that - improves readability, manageability of traffic profiles for various - test scenarios. + - **SRv6** -#. Added VPP performance tests + - Initial SRv6 (Segment Routing IPv6) tests verifying performance of + IPv6 and SRH (Segment Routing Header) encapsulation, decapsulation, + lookups and rewrites based on configured End and End.DX6 SRv6 egress + functions; - - **LXC memif** + - **IPSecSW** - - Memif interface tests interconnecting two VPP instances on single SUT. - Master VPP instance running on native OS with Intel x520 NIC and guest - VPP instance running in Linux Container (LXC) doing the L2 cross - connect loop. LXC running in privileged mode is pinned to dedicated - cores. All VPP instances are same version. + - SW computed IPSec encryption with AES-GCM, CBC-SHA1 ciphers, in + combination with IPv4 routed-forwarding; - - **Stateful Security Groups** +#. Presentation and Analytics Layer - - **VM vhost use cases** + - Added throughput speedup analysis for multi-core and multi-thread + VPP tests into Presentation and Analytics Layer (PAL) for automated + CSIT test results analysis; -Performance Improvements ------------------------- +#.

Note that the standard deviation is quite high for a small +number of packet throughput tests, what indicates poor test results +repeatability and makes the relative change of mean throughput value not +fully representative for these tests.
