Test environment changes in VPP data plane performance tests: - - - Further characterization and optimizations of VPP vhost-user and VM - test methodology and test environment; - - - Tests with varying Qemu virtio queue (a.k.a. vring) sizes: - [vr256] default 256 descriptors, [vr1024] 1024 descriptors to - optimize for packet throughput; - - - Tests with varying Linux CFS (Completely Fair Scheduler) - settings: [cfs] default settings, [cfsrr1] CFS RoundRobin(1) - policy applied to all data plane threads handling test packet - path including all VPP worker threads and all Qemu testpmd - poll-mode threads; - - - Resulting test cases are all combinations with [vr256,vr1024] and - [cfs,cfsrr1] settings; - - - For more detail see performance results observations section in - this report; - -#. Code updates and optimizations in CSIT performance framework: - - - Complete CSIT framework code revision and optimizations as descried - on CSIT wiki page - `Design_Optimizations `_. - - - For more detail see the CSIT Framework Design section in this - report; - -#. Changes to CSIT driver for TRex Traffic Generator: - - - Complete refactor of TRex CSIT driver; - - - Introduction of packet traffic profiles to improve usability and - manageability of traffic profiles for a growing number of test - scenarios. - - - Support for packet traffic profiles to test IPv4/IPv6 stateful and - stateless DUT data plane features; - -#. Added VPP performance tests - - - **Linux Container VPP memif virtual interface tests** - - - VPP Memif virtual interface (shared memory interface) tests - interconnecting VPP instances over memif. VPP vswitch - instance runs in bare-metal user-mode handling Intel x520 NIC - 10GbE interfaces and connecting over memif (Master side) virtual - interfaces to another instance of VPP running in bare-metal Linux - Container (LXC) with memif virtual interfaces (Slave side). LXC - runs in a priviliged mode with VPP data plane worker threads - pinned to dedicated physical CPU cores per usual CSIT practice. - Both VPP run the same version of software.
