Subject: [dpdk-dev] [PATCH 1/2] mempool: use a better default for number of memory channels
Date: Thu, 15 Oct 2015 14:49:04 +0300 [thread overview]
Message-ID: <924c845bd743e49683853a8127c165c6d7aa0ab0.1444909165.git.pmatilai@redhat.com> (raw)
In-Reply-To: <cover.1444909165.git.pmatilai@redhat.com>
In-Reply-To: <cover.1444909165.git.pmatilai@redhat.com>
Optimize for quad-channel by default, this should work well for
all the cases, better than the previous value of one anyway.
