Subject: [dpdk-dev] [PATCH v2 5/6] app/regex: support performance measurements per QP
Date: Sun, 20 Dec 2020 10:41:47 +0000
Message-ID: <20201220104148.13961-6-ophirmu@nvidia.com> (raw)
In-Reply-To: <20201220104148.13961-1-ophirmu@nvidia.com>

Up to this commit measuring the parsing elapsed time and Giga bits per
second performance was done on the aggregation of all QPs (per core).
This commit separates the time measurements per individual QP.
