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?
The full report can be found here:

* Mellanox CX-5 (mlx5) shows significant improvement
* Ixgbe shows improvement
Thanks,
