Hi All, Significant performance degradation observed with DPDK 17.11 The Scenario is with TRex traffic generator (https://github.com/cisco-system-traffic-generator/trex-core)
1. Stateless mode, 64B packet stream (multi-core/single core) DPDK 17.02 - 37-39MPPS/core DPDK 17.11 - 33.5MPPS/core ~12% degradation 2. Stateless mode, Field Engine (Multi-core) DPDK 17.02 - 14MPPS/core DPDK 17.11 -11.8MPPS/core ~15% degradation 3. Only DPDK was replaced 4. Is this expected?
