Subject: [dpdk-dev] [PATCH v2] mlx5: fix RETA table size
Date: Thu, 31 Mar 2016 12:21:08 +0300 [thread overview]
Message-ID: <1459416068-11773-1-git-send-email-yaacovh@mellanox.com> (raw)
In-Reply-To: <1459351639-18375-1-git-send-email-yaacovh@mellanox.com>
When the number of RX queues is not a power of two,
the RETA table is configured to its maximum size for
better balancing.
Testing showed that limiting its size to 256 improves performance
noticeably with little to no impact on balancing results.
Fixes: ebb30ec64a68 ("mlx5: increase RETA table size")
