Hi Thomas and John,

We found that the performance degradation is not related to DPDK 17.02 for =
Intel XL710/ixgbe.  Now It is back to normal. The fix was to add a one unre=
lated line to a specific file. This probably changed the instructions trace=
. This line is not related to DP or CP. (We still don't fully understand th=
at).
Mlx5 small degradation wasn't solved yet.=20

Thanks,
Hanoh

+1 for the bisect.
Please could you try to isolate the change causing the regression?
