--- title: "VPP Performance" weight: 1 --- # Changes in {{< release_csit >}} 1. VPP PERFORMANCE TESTS - **Enhanced and added VPP hoststack tests** to daily and weekly trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3, LD_PRELOAD NGINX. - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending and report, in addition to RDMA_CORE ones that were already there. - **Jumbo frames tests** got fixed and re-added number of to report coverage tests. - **Intel Xeon SKX performance testbeds** got decommissioned and removed from FD.io performance lab. 2. TEST FRAMEWORK - **CSIT test environment** version has not changed from ver. 11 used in previous release, see [Environment Versioning]({{< ref "infrastructure#Release Notes" >}}). - **CSIT PAPI optimizations for scale** got applied improving PAPI programming speed especially for large scale tests. VAT has been now completely deprecated from CSIT. - **General Code Housekeeping**: Ongoing code optimizations and bug fixes. 3. PRESENTATION AND ANALYTICS LAYER - [Performance dashboard](https://csit.fd.io/) got updated with addition of VPP telemetry trending across all VPP tests. A number of code and AWS resource usage optimizations got applied to the data processing pipeline and UI frontend and backend. - Examples of release iterative data visualisation: - [Packet throughput 2n-icx-e810cq-ip4-base-scale-pdr](https://csit.fd.io/report/#eNrdVcluwjAQ_Zr0ggbZDml64QDkP5BxhhJlwYxNVPr1OAhpYiGO7cEHb3pv1qeRnT8T7h1266zYZuU2U2VThy3LN4twUOdULhSM1oLKl-FG2KF2CGqAxvyAFOIblZX4JYW5gB6P0NgVfK4OIA2gP02vsA6Tja1pcq12T9cvcRitr57RED1CRiQGo7SYZk-3GeddsszXhJoNQsYMeXSzZOKamHUk3aNrfpGpoQuMm9BohqSJ_fubnaHPRpXVg_F3qjijO1RCtEBDnZo8UXFJ6NQmKlGbgjp9ujPU_8cEFdXHcKb-8Q8V1R2PI8PX) - [Speedup Multi-Core throughput graph for 2n-icx-e810cq-ip4-base-pdr](https://csit.fd.io/report/#eNrtlM8OgjAMxp8GL6aGFRAvHlTew8xRhAR1bpOoT-8wJIUYEg8mXjjsX35fu65fMusuhvaW6nWQbIN0G2Ba5X4Kos3cL6a2GIUIjdaA0cLvDNUkLQGeoVJ3EGF4JNSCViJUV5BNAZWOYRkfQCggV7YnPw5tjM5Nmxp3XeqPe5jmN8fU3z4gDRmGg7JYpstHTzNWLOulIckBvmJGjmyvmOGbWFUYeSJbPYmlvgvMlW80I6GG-d1D92jXqDR7K37qCk6ujLuC_3IlnlwZdyX-0pUkm50v5vT-yZLsBXP6Swk>) - [MRR, NDR and PDR comparison for 2n-icx-e810cq-ip4-base](https://csit.fd.io/report/#eNrtVMsOgjAQ_Bq8mDW0gHjxoPIfppZVSQDrthLx6y2GuBBj4kVPHvrKzG6nM0mtOxFuLZbLIFkH6TqQaZH7KYhWU79QaWUUSmiMARnN_I6wRGURZA2FvoIIwwNKI3AhQn0G1eyhMDHM4x0IDeiO3cmPXVdTEXWt5aZv_XIPo_nFMepvHyENEoMjWUwzx3bAeSeW-YpQcYFXzJBDOxAzfhOz9qQqtMUNmepdYFx7oxkSetzftWaA9kal2YPx5VTq_J_KR6n0Rv0mFfNP5bNUzDOVJJvUJ6oeP1mS3QG2H0sT>) - [Normalized throughput architecture comparison for 2n-[icx|clx]-e810cq-ip4-base-pdr](https://csit.fd.io/report/#eNrVk00OgjAQhU-DGzOGFhA3LlTuYUoZhKRibSsRT28hJANRF-500b98rzOvM6l1F4NHi2obJPsg3Qc8rQs_BdFu6RejLI9CDq3WwKOV3xlUKCwCb0CqO7AwPCHXDDcslFcQbQm1jmEd58AkoKv6kx95f0cXpg_ND2PolzxEi5sj6rPPSIuG4MwWyXTVTTSfzJJeGBR0wTsm5NBOzMzfRKrSiDPa-oEk9VUgLn2hCTE5j-86PaFjodJsUHzXlVr-UVfem_35riTZormY8_BneNpvhRpzJNkT6FzkMw>) - [NICs comparison for 2n-icx-ip4-base-pdr](https://csit.fd.io/report/#eNrll99ugyAUh5_G3SxnESx1N7to53s0FI6rmbYMnKF7-qFrcmRmV7vReuG__A74wSckuvZi8eCwfknEPsn3Cc8rHU5JtnsMF1s7nqUcOmOAZ0_hzmKN0iHwM6jaA0vTN-SGKS_EVkJTewGV2cB2cwSmANtT_xSOY9_IaNv3zV9vfU9eRKn-bCkNr4-SDi2FEReVmdN1VPMnLTWQFiW1CMgUtehGNPGgqKq0skFXfSGVhmmgXIWppoipuP_2akbpbabyYqj4txerG7kcLz3tnXvBZ5aqD5BduQAtBLsOK9ro9-Vo6Wnv1sswUJ-zdPZLJSJdgY_ZL5IY9U6NcPEzTN8NX14JXpsZW_mNewi46zAz691rwroKJzPfwaaws7ciiofzxTbDv6QovgETwNPp>) # Known Issues Editing Note: below listed known issues need to be updated to reflect the current state as tracked on [CSIT TestFailuresTracking wiki](https://wiki.fd.io/view/CSIT/TestFailuresTracking). ## New **#** | **JiraID** | **Issue Description** -------|--------------------------------------------------|------------------------------------------------------ 1 | [CSIT-1890](https://jira.fd.io/browse/CSIT-1890) | 3n-alt: Tests failing until 40Ge Interface comes up. ## Previous Issues reported in previous releases which still affect the current results. **#** | **JiraID** | **Issue Description** -------|-------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1 | [CSIT-1782](https://jira.fd.io/browse/CSIT-1782) | Multicore AVF tests are failing when trying to create interface. Frequency is reduced by CSIT workaround, but occasional failures do still happen. 2 | [CSIT-1785](https://jira.fd.io/browse/CSIT-1785) [VPP-1972](https://jira.fd.io/browse/VPP-1972) | NAT44ED tests failing to establish all TCP sessions. At least for max scale, in allotted time (limited by session 500s timeout) due to worse slow path performance than previously measured and calibrated for. CSIT removed the max scale NAT tests to avoid this issue. 3 | [CSIT-1799](https://jira.fd.io/browse/CSIT-1799) | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. 4 | [CSIT-1800](https://jira.fd.io/browse/CSIT-1800)
