From: Pablo de Lara Date: Thu, 23 Jul 2015 16:12:07 +0000 (+0100) Subject: examples/l3fwd: increase lookup burst size to 8 X-Git-Tag: spdx-start~8628 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=80fcb4d4;p=dpdk.git 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.
