Hi, Pablo
Is there any performance data for this change?
Thanks,

Subject: [dpdk-dev] [PATCH] examples/l3fwd: increase lookup burst size to 8
With the new hash implementation, the minimum lookup burst size to get good performance is 8, since its internal pipeline consists of 4 stages of 2 entries each, so to avoid duplication, burst size should be 8 or more entries.
