Subject: [dpdk-dev] [PATCH v5 16/25] mlx5: replace countdown with threshold for Tx completions
Date: Thu, 23 Jun 2016 19:05:14 +0200	[thread overview]
Message-ID: <1466700801-10383-11-git-send-email-nelio.laranjeiro@6wind.com> (raw)
Message-ID: <20160623170514.C9cVXT2Pvxm9dIZQIF8-ESpyReHetnfmS0_zHeNMF7A@z> (raw)
In-Reply-To: <1466700801-10383-1-git-send-email-nelio.laranjeiro@6wind.com>

From: Adrien Mazarguil <adrien.mazarguil@6wind.com>

Replacing the variable countdown (which depends on the number of
descriptors) with a fixed relative threshold known at compile time improves
performance by reducing the TX queue structure footprint and the amount of
code to manage completions during a burst.

Completions are now requested at most once per burst after threshold is
reached.
